A cube has edge length 5in use a exponent to express volume

5 cubed (or an exponent of three)

What exponents do you know that share names with different kinds of shapes? It may surprise you (or not) to discover that taking the square of a number and taking the cube of a number both derive their names from finding the space inside a square and a cube respectively. For squaring (as in x²) this corresponds to calculating the area of a square with side lengths x. For cubing (as in x³), it corresponds to calculating the volume of a cube with edge lengths x.

So, if we want to find the volume of a cube with edge length 5 in, we just need to find the value of 5³. (Keep in mind that our final units will be in in³)
