Answer:
4608 cubes
Explanation:
It is very important to note that:
1 cube in a Rectangular Prism has a side length of 1/4
The volume of 1 cube = (side length)³
= (1/4)³ cubic units
We are told in the above question that:
A rectangular prism has a volume of 72 cubic units.
The number of unit cubes that will fill the rectangular prism exactly is calculated as:
72 cubic units ÷ (1/4)³ cubic units
= 72 cubic units ÷ (1/64) cubic units
= (72 × 64 ) cubes
= 4608 cubes
Therefore, the number of unit cubes that will fill the rectangular prism exactly is 4608 cubes
