Answer:
125 cubic inches
Step-by-step explanation:
The formula for the volume of a cube is:
[tex]V=a^3[/tex],
Where V is volume and a is edge length. Let's substitute the edge length of 5 from the problem into this formula.
[tex]V=5^3[/tex]
Now we can simplify. I will rewrite 5 cubed as 5*5*5 for simplicity.
[tex]V=5*5*5[/tex]
[tex]V=125[/tex]
So we have our volume, 125, but what does this mean? We have to figure out the units. Recall that our original unit was inches, thus the final answer is in inches. However, 125 inches does not make much sense, as we are dealing with volume, and not a line or distance. 125 cubic inches is the answer we are looking for, as cubic inches is the unit for volume deriving from inches.
