Where V is the volume and a is the edge length.

volume of a cube

Example Problems

Problem 1:
Find the volume of a cube with an edge length of 5.
Solution:
1.) We can simply plug the edge length into the formula. This gives us:
V = a3
V = (5)3 = 125
2.) The volume of the cube is 125.

Problem 2:
The volume of a cube is 343. What is the edge length?
Solution:
1.) Let’s plug the volume into the formula and then solve for the edge length a.
2.) V = a3
343 = a3
3√343 = a
a = 7
3.) The edge length is 7.
