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:

n=90

Step-by-step explanation:

As I think it is easy to answer the volume of prism I will also calculate no of small prism that can fit inside the larger one  

so volume = length * width * height

volume of larger prism

vp=45/4 ft^3 =11.25

volume of small cubes

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

vs=0.125 ft^3

now numbers of cube that can fit

n=vp/vs

n= 11.25/.125

n=90

so 90 smaller cubes will completely fill in the prism
