Question

find the volume of a cube whose side is 7.5 dm​

Answer 1

GivEn:

• Side of cube = 7.5dm

To finD:

• Volume of cube

Solution:

Here, given that side of cube is 7.5dm.

We know that :

Volume of cube = side³

Putting values in formula :

Volume of cube = side³

=> V. of cube = (7.5)³

=> V. if cube = 7.5 × 7.5 × 7.5

=> V. of cube = 56.25 × 7.5

=> V. of cube = 421.875

Therefore,

Volume of given cube is 421.875dm³
