9. The formula V=lwh is the volume formula for a rectangular prism. Find the length (l) of a prism with volume (V) 1200 cm³, width (w) 15 cm, and height (h) 8 cm.

A. 6 cm
B. 8 cm
C. 10 cm
D. 14 cm

Answer 1

C. 10cm

Explanation:

First we can rearrange the equation to solve for length (l):

V = lwh

Divide both sides by wh:

l = V/(wh)

Substitute in known values:

l = 1200/(15x8)

l = 1200/120

l = 10cm
