Volume of a Cube Lesson
Cube Volume Formula
The formula for volume of a cube is given as:
V = a3
Where V is the volume and a is the edge length.
INTRODUCING
Volume of a Cube Example Problems
Let's go through a couple of example problems together to practice finding the volume of a cube.
Example Problem 1
Find the volume of a cube with an edge length of 5.
Solution:
- We can simply plug the edge length into the formula. This gives us:
- V = a3
- V = (5)3 = 125
- The volume of the cube is 125.
Example Problem 2
The volume of a cube is 343. What is the edge length?
Solution:
- Let's plug the volume into the formula and then solve for the edge length a.
- V = a3
- 343 = a3
- 3√343 = a
- a = 7
- The edge length is 7.
