Question

FAN & MEDAL. HALP.
A box is x inches high, (2x + 3) inches wide, and (2x + 5) inches long. In terms of x, what is the volume (V) of the box?

A) V = 4x3 + 15x
B) V = 4x3 + 4x2 + 5x
C) V = 4x3 + 4x2 + 15x
D) V = 4x3 + 16x2 + 15x

Answer 1

Volume of a box = height * width * length

So you want to multiply all the values given to you.
\[V = x(2x+3)(2x+5)\]
^This is the equation and you just need to expand everything :)
