A right rectangular prism has a length of 2 ½ feet, a width of 3 feet, and a height of 1 ½ feet. Unit cubes with side lengths of ½-foot are added to completely fill the prism with no space remaining. What is the volume, in cubic feet, of the right rectangular prism?

Answer:

volume = length * width * height

volume of larger prism

vp= 45/4ft^3 = 11.25

volume of small cubes

vs = 1/2 * 1/2 * 1/2

vs = 0. 125ft^3

now number of cube that can fit

n = vp/vs

n=11.25/.125

n=90

so 90 smaller cubes will completely fill in the prism.
