Q4 of 45 Page 11

Suppose that there are two cubes, having edges 2 cm and 4 cm, respectively. Find the volumes V1 and V2 of the cubes and compare them.

Given: a1 = 2 cm


a2 = 4 cm


To find: Volumes V1 and V2 and compare them


Formula Used: Volume of cube = a3


Explanation:


a1 = 2 cm


V1 = 23


=8 cm3


a2 = 4 cm


V2 = 43


=64 cm3


Hence,


V2 = 8 V1
