the length of a rectangular prism is 4 feet, and the width is 3 feet. The volume of the prism is 9 cubic feet. In inches, what is the height of the prism?
A) 6 inches
B) 8 inches
C) 9 inches
D) 10 inches

Respuesta :

The formula for volume of a rectangular prism is V = lwh.  Plugging in what we have:
9 = 4(3)(h)
9 = 12h
Now we cancel the 12 by dividing:
9/12 = 12h/12
3/4 = h
However, this is in feet.  We must convert to inches:
3/4 (12) = 3/4(12/1) = 36/4 = 9 inches.

Answer:

C 9 inches
