Answer:
8000 in³ because 20 × 20 × 20 is 8000
Answer and Step-by-step explanation:
We are given:
Each side of the box is 20 inches.
A side of the box is denoted as s.
The volume of a cube is [tex]V=s^{3}[/tex]
If s is a side of the box, and one side of the box is 20 in., then that means s is equal to 20.
So, to find the volume, we plug 20 in for s in the volume equation.
[tex]V = 20^{3}[/tex]
(This is the same as saying 20 times 20 times 20).
V = 8,000 [tex]in^{3}[/tex]
