small cubes of edge 2cm are to be packed into a rectangular container measuring 6cm by 5m and 4m .How many cubes are required?

Answer»

Answer:

$\bigstar{\bold{<klux>NUMBER</klux>\:of\:cubes=15}}$

Step-by-step explanation:

$\Large{\underline{\sf{Given:}}}$

Edge of small cube = 2 CM
Dimensions of the rectangular container = 6 cm × 5 cm × 4 cm

$\Large{\underline{\sf{To\:Find:}}}$

Number of cubes that are required

$\Large{\underline{\sf{Solution:}}}$

➵ Here we have to find how many cubes can be packed into the rectangular container.

➵ First we have to find the volume of the cube.

➵ Volume of a cube is given by,

Volume of a cube = a³

where a is a SIDE of the cube

➵ Substitute the data,

Volume of the cube = 2³

Volume of the cube = 8 cm³

➵ Hence volume of each of the cube is 2 cm³.

➵ Now finding the volume of the rectangular container which is in the shape of a cuboid,

➵ Volume of a cuboid is given by,

Volume of a cuboid = l × b × h

where l is the LENGTH

b is the breadth

h is the height

➵ Substitute the data,

Volume of rectangular container = 6 × 5 × 4

Volume of rectangular container = 120 cm³

➵ Hence volume of the container is 120 cm³.

➵ Now finding the number of cubes that can be packed into it,

➵ Number of cubes = Volume of container/Volume of cube

➵ Substituting the data,

Number of cubes = 120/8

Number of cubes = 15

➵ Hence 15 cubes can be packed inside the rectangular container.

$\boxed{\bold{Number\:of\:cubes=15}}$

17.	a man sold a watch for 600 rs at a loss . had he sold it for 750 rs , his gain would have been double the former loss . the cost price of the watch is ?
Answer» Step-by-step EXPLANATION: LET the cost PRICE of watch is Rs. x Then loss = Rs. x−600 If watch sold Rs. 750, then PROFIT = Rs. 750−x Given gain has been double the loss Then 750−x=2(x−600) ⇒750−x=2x−1200 ⇒x=650 Therefore, the cost price of the watch is Rs. 650.

17.

a man sold a watch for 600 rs at a loss . had he sold it for 750 rs , his gain would have been double the former loss . the cost price of the watch is ?

Answer»

Step-by-step EXPLANATION:

LET the cost PRICE of watch is Rs. x

Then loss = Rs. x−600

If watch sold Rs. 750, then PROFIT = Rs. 750−x

Given gain has been double the loss

Then 750−x=2(x−600)

⇒750−x=2x−1200

⇒x=650

Therefore, the cost price of the watch is Rs. 650.

34.	The sum of the digits of a two-digit number is 4 The numbes got by interchangingthe digits is 18 less than the originalnumber what is the number?
Answer» Let the Tens DIGIT be x the Ones digit be y We know that Sum of digits is 4 ⇒ x + y = 4 ⟶ (Equation 1) Original number: 10x + y On interchanging the digits → 10Y + x According to the question, (10x + y) - (10y + x) = 18 ⇒ 10x + y - 10y - x = 18 ⇒ 10x - x + y - 10y = 18 ⇒ 9x - 9y = 18 ⇒ 9(x - y) = 18 ⇒ x - y = 18 ÷ 2 ⇒ x - y = 2 ⟶ (Equation 2) Adding EQUATIONS 1 and 2, x + y = 4 (+) x - y = 2 2x = 6 ⇒ x = 3 Now let's Substitute value of x in any one of the equation. Here I have substituted value of x in Equation 1 x + y = 4 ⇒ 3 + y = 4 ⇒ y = 4 - 3 ⇒ y = 1 For finding the required number, 10x + y = 10(3) + 1 = 31 Therefore required number is 31

34.

The sum of the digits of a two-digit number is 4 The numbes got by interchangingthe digits is 18 less than the originalnumber what is the number?

Answer»

Let the Tens DIGIT be x

the Ones digit be y

We know that Sum of digits is 4

⇒ x + y = 4 ⟶ (Equation 1)

Original number: 10x + y

On interchanging the digits → 10Y + x

According to the question,

(10x + y) - (10y + x) = 18

⇒ 10x + y - 10y - x = 18

⇒ 10x - x + y - 10y = 18

⇒ 9x - 9y = 18

⇒ 9(x - y) = 18

⇒ x - y = 18 ÷ 2

⇒ x - y = 2 ⟶ (Equation 2)

Adding EQUATIONS 1 and 2,

x + y = 4

(+) x - y = 2

2x = 6

⇒ x = 3

Now let's Substitute value of x in any one of the equation.

Here I have substituted value of x in Equation 1

x + y = 4

⇒ 3 + y = 4

⇒ y = 4 - 3

⇒ y = 1

For finding the required number,

10x + y

= 10(3) + 1

= 31

Therefore required number is 31

Solve the following pairs of linear equation by substitution methoda) x + y = 14X - y = 4Ans:-b) 3x - y - 3 = 0X - 3y – 9 = 0Ans;

Answer»

ANSWER:

X + y = 14

x = 14 - y

substituting x = 14 - y in equation

x-y =14

(14 - y ) - y = 14

14-y -y = 4

14 - 2y = 4

y = 10 / 2

y = 5
