Volume of a cube is s^3 where s is the length of one side.
V = 64
s^3 = 64
Take the cube root of each side:
s = 4 since 4^3 = 64
Surface Area of a cube is 6s^2. With s = 4, we have:
SA = 6(4)^2
SA =6(16)
SA = 96
If cement cost $4 per cubic foot, how much does a cubic yard of cement cost?
There are 3 feet in a yard
3 x 3 x 3 = 27 cubic feet in a yard
Total cost = 27 cubic feet * $4 per cubic foot = $108
If V is the volume of a cube whose side is s, express s in terms of V:
We know the Volume (V) of a cube with side length s is:
V = s^3
Take the cube root of each side:
V^1/3 = (s^3)^1/3
s = V^1/3
A cupe-shaped tank has edge lengths of 1/2 foot. Sheldon used the expression s to the power of 3 = v to find the volume. What was the volume of the tank?
1/2 foot = 6 inches
v = (6)^3
v = 216 cubic inches
A cubical storage box has edges that are 2 feet 4 inches long. What is the volume of the storage box?
Since 1 foot = 12 inches, we have:
2 feet 4 inches = 2(12) + 4
2 feet 4 inches = 24 + 4
2 feet 4 inches = 28 inches
We type cube side = 28 into our search engine to get:
V = 21952 cubic inches
