<em><u>The volume of cube is given by formula:</u></em>

Where,
V is the volume of cube
"s" is the length of one side
<em><u>What is the volume of a cube if the length of a side s is 10 feet</u></em>
Given, s = 10 feet
<em><u>Substitute s = 10 in given formula,</u></em>

Thus volume of cube is 1000 cubic feet
