6.	Two cubes each of 8 cm edge are joined end to end. Find the surface area of the resulting cuboid.
Answer» Given - Edge of two cubes is 8cm To FIND - TOTAL SURFACE area of resulting cuboid. Formula used - Total surface area of cuboid. Solution - In the question, we are PROVIDED with the edge of two cubes i.e 8cm, and they are joined together from end to end. So, the length, Breadth and height of the resulting cuboid will be 8cm only, just the length will be different, as the cubes are joined from end to end, we will add 8cm to 8cm, after that we will further do this question. According to question - $\longrightarrow$ Length of cuboid = 8cm + 8cm = 16cm $\longrightarrow$ Breadth of cuboid = 8cm $\longrightarrow$ Height of cuboid = 8cm Total surface area of cuboid - $\sf \longrightarrow \: <klux>2</klux>(lb \: + \: bh \: + hl)$ On substituting the values - $\sf \longrightarrow \: TSA \: = 2(16cm)(8cm) \: + (8cm)(8cm) \: + (8cm)(16cm) \\ \\ \sf \longrightarrow \: TSA \: = 2(128cm\: + 64cm \: + 128cm) \\ \\ \sf \longrightarrow \: TSA \: = 2(320cm) \\ \\ \sf \: TSA \: = 640 {cm}^{2} \\ \\$ $\therefore$ The total surface area of the resulting cuboid is 640cm² 2 more formulae (of cuboid) 1.

6.

Two cubes each of 8 cm edge are joined end to end. Find the surface area of the resulting cuboid.

Answer»

Given -

Edge of two cubes is 8cm

To FIND -

TOTAL SURFACE area of resulting cuboid.

Formula used -

Total surface area of cuboid.

Solution -

In the question, we are PROVIDED with the edge of two cubes i.e 8cm, and they are joined together from end to end. So, the length, Breadth and height of the resulting cuboid will be 8cm only, just the length will be different, as the cubes are joined from end to end, we will add 8cm to 8cm, after that we will further do this question.

According to question -

$\longrightarrow$ Length of cuboid = 8cm + 8cm = 16cm

$\longrightarrow$ Breadth of cuboid = 8cm

$\longrightarrow$ Height of cuboid = 8cm

Total surface area of cuboid -

$\sf \longrightarrow \: <klux>2</klux>(lb \: + \: bh \: + hl)$

On substituting the values -

$\sf \longrightarrow \: TSA \: = 2(16cm)(8cm) \: + (8cm)(8cm) \: + (8cm)(16cm) \\ \\ \sf \longrightarrow \: TSA \: = 2(128cm\: + 64cm \: + 128cm) \\ \\ \sf \longrightarrow \: TSA \: = 2(320cm) \\ \\ \sf \: TSA \: = 640 {cm}^{2} \\ \\$

$\therefore$ The total surface area of the resulting cuboid is 640cm²

2 more formulae (of cuboid)

1. Lateral surface area = 2h(l + b)

2. Volume = L × B × H

Find the height of a cuboid with length 10m , breadth 5m , volume 62.5m^3

Answer»

AnswEr-:

$\boxed {\mathrm { Height\:of\:Cuboid = 1.25 m}}$

Explanation-:

$\sf{Given-:}$

The LENGTH of Cuboid is 10 m
The Breadth of Cuboid is 5 m
The VOLUME of Cuboid is 62.5m³

$\sf{To\:Find-:}$

The height of Cuboid.

$\dag{\underline {\mathrm{Solution \:of\:Question \:-: }}}$

$\underbrace{\mathrm{Understanding \:the\:Concept-:}}$

We have to Find the Height of Cuboid when Length, Breadth and Volume of cuboid is given or known .

For this we have to put the known or Given Values in Formula for Volume of Cuboid then ,

We can get the height of the Cuboid,.

As We KNOW that -:

$\underline{\boxed{\mathrm {\dag{\red{ Volume _{(Cuboid)}-: Length \times Breadth\times Height \:or\:lbh\:cube.units}}}}}$

Here ,

The length of Cuboid is 10 m
The Breadth of Cuboid is 5 m
The Volume of Cuboid is 62.5m³
The Height of Cuboid is ??

Now , By Putting Known or Given Values in the Formula for Given of Cuboid-:

$\longrightarrow {\mathrm {10 \times 5 \times Height = 62.5 m^{3}}}$

$\longrightarrow {\mathrm { 50 \times Height = 62.5 m^{3}}}$

$\longrightarrow {\mathrm {Height = \dfrac{62.5}{50} }}$

$\longrightarrow {\mathrm {Height = \dfrac{\cancel {62.5}}{\cancel {50}} }}$

$\longrightarrow {\mathrm { Height = 1.25 m}}$

Hence ,

$\boxed {\mathrm { Height\:of\:Cuboid = 1.25 m}}$

____________________________________

$\huge{\dag{\mathrm{Verification-:}}}$

$\underline{\boxed{\mathrm {\dag{\red{ Volume _{(Cuboid)}-: Length \times Breadth\times Height \:or\:lbh\:sq.units}}}}}$

Here ,

The length of Cuboid is 10 m
The Breadth of Cuboid is 5 m
The Volume of Cuboid is 62.5m³
The Height of Cuboid is 1.25 m

Now , By Putting Known or Given Values in the Formula for Given of Cuboid-:

$\longrightarrow {\mathrm {10 \times 5 \times 1.25 = 62.5 m^{3}}}$

$\longrightarrow {\mathrm {50 \times 1.25 = 62.5 m^{3}}}$

$\longrightarrow {\mathrm {62.5m^{3} = 62.5 m^{3}}}$

Therefore,

$\longrightarrow {\mathrm {LHS= RHS}}$
$\longrightarrow {\mathrm {Hence\:Verified!}}$

2-3x > 1 (x belongs to -3 ,-2 ,-1 ,0,1,2,3)

Answer»

ANSWER:

None of the given

To Find:

VARIABLE X

Given:

2 - 3X > 1

(2 - 3x = LESS than 1)

So, let's try all numbers.

1. X = 3

= 2 - 3x

= 2 - 3(3)

= 2 - 9

= -7

2. X = 2

= 2 - 3x

= 2 - 3(2)

= 2 - 6

= -4

3. X = 1

= 2 - 3x

= 2 - 3(1)

= 2 - 3

= -1

4. X = 0

= 2 - 3x

= 2 - 3(0)

= 2 - 0

= 2

5. X = -1

= 2 - 3x

= 2 - 3(-1)

= 2 + 3

= 5

6. X = -2

= 2 - 3x

= 2 - 3(-2)

= 2 + 6

= 8

7. X = -3

= 2 - 3x

= 2 - 3(-3)

= 2 + 9

= 11

19.

Question ⤵Without actual division, prove that Is exactly divisible by No spams needed. Quality Answers needed. A. S. A. P.

Answer»

Step-by-step explanation:

suppose x⁴+2x³-2x²+2x-3 = F(x)

x²+2x-3 = 0

=> x²+(3-1)x-3 = 0

=> x²+3x-x-3 = 0

=> x(x+3)-1(x+3) = 0

=>(x+3)(x-1) = 0

=> x = -3 => x = 1

-3 and 1 are the ROOTS of x²+2x-3 = 0

if x⁴+2x³-2x²+2x-3 is divisible by x²+2x-3 then f(-3) and f(1) = 0

f(-3) = (-3)⁴+(2*(-3)³)-(2*(-3)²)+(2*(-3))-3

= 81+(2*(-27))-(2*9)-6-3

= 81-54-18-6-3

= 81-81

= 0

f(1) = (1)⁴+(2*(1)³)-(2*(1)²)+(2*(1))-3

= 1+2-2+2-3

= 5-5

= 0

this is proved that x⁴+2x³-2x²+2x-3 is divisible by x²+2x-3

X +1/x=3 then find x⁵+1/x⁵=? Please give full explanation.

Answer»

Step-by-step EXPLANATION:

Given:-

X +1/x=3

To find:-

find x⁵+1/x⁵

Solution:-

Given that

x + 1/x =3 -----------(1)

on squaring both sides then

(x + 1/x )^2=3^2

=>x^2 + 2(x)(1/x) + (1/x)^2 =9

(since (a+b)^2=a^2+2ab+b^2)

=>x^2 + 2 + (1/x)^2 =9

=>x^2 + (1/x)^2 = 9-2

x^2 + (1/x)^2 = 7 -------(2)

On cubing both side of the equation (1) then

(x + 1/x)^3=3^3

(since (a+b)^3 = a^3+ b^3 +3AB(a+b))

=>x^3 +1/x^3+ 3(x)(1/x)(x+1/x)=27

=>x^3+1/x^3+3(3)=27 (from(1))

=>x^3+1/x^3+9=27

=>x^3+1/x^3=27-9

=>x^3+1/x^3=18-------(3)

Now multiplying (2)&(3)

(x^2+ 1/x^2)(x^3+1/x^3)=7×18

=>(x^2×x^3)+(x^2/x^3)+(x^3/x^2)+(1/x^2×1/x^3)=126

=>x^5+ 1/x +x + 1/x^5=126

=>x^5 + 1/x^5 + 3=126

=>x^5+1/x^5=126-3

x^5+1/x^5=123

Answer:-

The value of x^5+1/x^5=123

Used formulae:-

(a+b)^2=a^2+2ab+b^2
(a+b)^3=a^3+b^3+3ab(a+b)

38.	Find the altitude and area of an isoscles triangle whose perimeter is 32cm and whose base is 12cm
Answer» ★Given:- For an isosceles triangle, Perimeter = 32cm Base = 12cm ★To find:- ALTITUDE Area ★Solution:- Let the congruent sides of the isosceles triangle =a The base =b We know, ✦Perimeter of the triangle = SUM of all sides Putting values, →a + a + b =32 →2a+12=32 →2a = 20 →a = 20/2 →a=10cm Therefore,length of the congruent sides of the triangle is 10cm. The altitude of the triangle divides it into two RIGHT angled triangles, For each equal triangle, Hypotenuse = 10 cm Base = (12/2) Base = 6 cm By pythagoras theorem, Height = √hypotenuse² - base² = √(10)² - (6)² = √100 - 36 = √64 = 8 cm Therefore,altitude = 8 cm. Using the FORMULA, ✦Area = 1/2(Base × Height) Putting values, →Area = (12 ×8)/2 cm² →(96/2) cm² →48 cm² ∴The area of the triangle is 48 cm². ________

Find the altitude and area of an isoscles triangle whose perimeter is 32cm and whose base is 12cm

Answer»

★Given:-

For an isosceles triangle,
Perimeter = 32cm
Base = 12cm

★To find:-

ALTITUDE
Area

★Solution:-

Let the congruent sides of the isosceles triangle =a

The base =b

We know,

✦Perimeter of the triangle = SUM of all sides

Putting values,

→a + a + b =32

→2a+12=32

→2a = 20

→a = 20/2

→a=10cm

Therefore,length of the congruent sides of the triangle is 10cm.

The altitude of the triangle divides it into two RIGHT angled triangles,

For each equal triangle,

Hypotenuse = 10 cm

Base = (12/2)

Base = 6 cm

By pythagoras theorem,

Height = √hypotenuse² - base²

= √(10)² - (6)²

= √100 - 36

= √64

= 8 cm

Therefore,altitude = 8 cm.

Using the FORMULA,

✦Area = 1/2(Base × Height)

Putting values,

→Area = (12 ×8)/2 cm²

→(96/2) cm²

→48 cm²

∴The area of the triangle is 48 cm².
