Answer 2

Given :

Edge of cube is 40 cm  

To Find :

Find the volume and surface area of a cube whose edge is 40 cm

Solution:

Edge of cube = 40 cm  

Volume of cube =$Side^3$

Volume of cube = $40^3$

Volume of cube =$64000 cm^3$

Surface area of cube = $6a^2=6(40)^2=9600 cm^2$

Hence the volume of cube is 64000 cubic cm and the surface area of cube is 9600 cubic cm
