12.	a godown is in the form of a cube side 40 cm how many cubical boxes can be stored in it? if the volume of one box is 8 metre cube?
Answer» Answer: 8000 Step-by-step explanation: Given-----> Godown is in the form of a cube of side 40Cm and volume of cubical BOX is 8 m³. To find -----> Nuumber of cubical boxes that can be stored in godown . Solution-----> ATQ, Side of cubical godown = 40 Cm Volume of cubical godown = Side³ = ( 40 )³ = 64000 Cm³ ATQ, Volume of ONE cubical box = 8 m³ Number of boxes that can be stored in godown = Volume of godown / Volume of one box = 64000 / 8 = 8000 Additional information-----> 1) Lateral surface area of cube = 4 ( side )² 2) Total surface area of cube = 6 side² 3) Volume of cuboid = l × b × h 4) Lateral surface area of cuboid = 2 ( l + b ) h 5) Total surface area of cuboid = 2 ( LB + bh + lh )

a godown is in the form of a cube side 40 cm how many cubical boxes can be stored in it? if the volume of one box is 8 metre cube?

Answer»

Answer:

8000

Step-by-step explanation:

Given-----> Godown is in the form of a cube of side 40Cm and volume of cubical BOX is 8 m³.

To find -----> Nuumber of cubical boxes that can be stored in godown .

Solution-----> ATQ,

Side of cubical godown = 40 Cm

Volume of cubical godown = Side³

= ( 40 )³

= 64000 Cm³

ATQ,

Volume of ONE cubical box = 8 m³

Number of boxes that can be stored in godown

= Volume of godown / Volume of one box

= 64000 / 8

= 8000

Additional information----->

1) Lateral surface area of cube = 4 ( side )²

2) Total surface area of cube = 6 side²

3) Volume of cuboid = l × b × h

4) Lateral surface area of cuboid

= 2 ( l + b ) h

5) Total surface area of cuboid

= 2 ( LB + bh + lh )

The sum of the ages of a son and his father is 36 years. After 6 years the age of father will be 5 times that of his son. Find their present agesAnswer only if you know the correct answer

Answer»

let the age of son be x years and the age of father be ( 36 - x ).

After 6 year.

son' s age = x + 6

Father ' s age = (36-x) + 6 = (42+x)

According to question ,

5 (x+6) = ( 42- x)

5x + 30 = 42 - x

5x + x = 42 - 30

6x = 12

x = 2

Therefore ,

The present age of son is 2 year ,

The present age of father is 34 year.

Answer» Answer: L=180 CMS, W=120CMS Step-by-step explanation: GIVEN L=SOME x and w=2/3 (L) from this we can say 1/3 is diff between L AND w given width incrased by 30 and length decreased by 30 makes it SQAURE range for width and length =60 (30+30) if 1/3 =60 then 1=? (160)/1/3=180 L=180 w=2/3(180)=120 for proof increase and DECREASE width and LENGHT by 30 respectively to get a sqaure .which is 150150 thus L=180 CMS, W=120CMS.... pls mark as brainliest for my effort

the width of the room is two third of its length. if the width had been 30 cm more and length 30 cm less it would have been a square . Find the length and breadth .

Answer»

Answer:

L=180 CMS, W=120CMS

Step-by-step explanation:

GIVEN L=SOME x

and w=2/3 (L)

from this we can say 1/3 is diff between L AND w

given width incrased by 30 and length decreased by 30 makes it SQAURE

range for width and length =60 (30+30)

if 1/3 =60

then 1=?

(1*60)/1/3=180

L=180

w=2/3(180)=120

for proof increase and DECREASE width and LENGHT by 30 respectively to get a sqaure .which is 150*150

thus L=180 CMS, W=120CMS....
