Question

The side length, s, of a cube is 4x2 + 3. If V = s3, what is the volume of the cube?

Answer 1

Answer: the volume of cube is 64 x6 + 144x4 + 108x2 + 27.

Explanation:

As given in the problem statement the volume

V = s3----- (1)

And

s = 4x2 + 3--------(2)

Hence,

the volume is obtained by substituting (2) in (1).

We get,

V = (4x2 + 3)3

= 64 x6 + 144x4 + 108x2 + 27

Therefore,

the volume of cube is 64 x6 + 144x4 + 108x2 + 27
