To find the volume of a cube with an edge length of 3 feet, follow these steps:
1. Identify the formula: The formula to find the volume (V) of a cube is given by [tex]\( V = a^3 \)[/tex], where [tex]\( a \)[/tex] is the length of an edge of the cube.
2. Substitute the given edge length: Here, the edge length [tex]\( a \)[/tex] is 3 feet.
3. Calculate the volume:
[tex]\[
V = 3^3
\][/tex]
4. Compute the power:
[tex]\[
3^3 = 3 \times 3 \times 3
\][/tex]
5. Perform the multiplication:
[tex]\[
3 \times 3 = 9
\][/tex]
[tex]\[
9 \times 3 = 27
\][/tex]
Thus, the volume of the cube is:
[tex]\[
V = 27 \text{ cubic feet}
\][/tex]
So, the volume, in cubic feet, of a cube with an edge length of 3 feet is [tex]\( \boxed{27} \text{ feet}^3 \)[/tex].
