Question

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

Answer 1

121 units²

Explanation:

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

Volume = s³

s = 4×2+3

so

(4 × 2 + 3)² = (remember PEMDAS)

(8 + 3)² =

11² =

121 units²

Answer 2

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

Step-by-step 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.
