Question

The length of a rectangular speaker is three times its width and the height is four more than the width. Write an expression for the volume V of the rectangular prism in terms of its width, w.

Formula: V = (length)(height)(width)


L=
W=
H=

Answer 1

Explanation:

W = w

L = 3w

H = w+4

Now V = LHW

= (3w)(w+4)(w)

= (3w²+12w)(w)

= 3w³+12w²
