Answer:
70 unit cubes
Explanation:
How many unit cubes are to make a model of a rectangular prism that is 7 units long, 2 units wide, and 5 units tall?
Step 1
We have to find the volume of the rectangular prism
The formula = Length × Width × Height
= 7 units × 2 units × 5 units
= 70 cubic units
Step 2
It is important to note that:
The volume of a unit cube is one cubic unit.
Volume of the rectangular prism = 70 cubic units
The number of unit cubes that would make the model above = 70
1 cubic units = 1 unit cube
70 cubic units = x
x = 1 × 70
x = 70 unit cubes
