Answer:

Step-by-step explanation:
The surface area of a cube-shaped box with a side of m feet is given by the function:

The cost, C, in dollars, of wrapping a box with a surface area of x square feet is given by the function:

We want to find an explicit expression that models the costs of wrapping a cube-shaped box with a side length of m feet.
In the cost function, C(x), x is the surface area, therefore:

To find the cost of wrapping a cube of side length m feet, we use the explicit function:
Answer:
8*29=232
