Question

If the length of side of a cube is doubled, then the ratio of volumes of new cube and original cube is –The area of a trapezium is 1586 cm2 and sum of parallel sides is 122cm. find the distance between two parallel sides.​

Answer 1

Answer:

Let the length of orignal cube =a.

Then, Volume of original cube V

1

=a

3

When side is doubled, length of side =2a.

Then, Volume of new cube =V

2

=(2a)

3

=8a

3

Therefore, the require ratio =

V

1

V

2

=

a

3

8a

3

=

1

8

=8:1.
