Question: A rectangular prism has a volume of 384 cm³, a length of 8 cm, and a height of 12 cm. What is the width of the prism?
(A) 4 cm
(B) 6 cm
(C) 8 cm
(D) 10 cm
Solution:
Use the volume formula for a rectangular prism:
V=l×w×h
Given V=384 cm³, l=8 cm, and h=12 cm:
384=8×w×12
384=96w
w= 384⁄96
w= 4 cm
