The formula for the volume of a rectangular prism is\[V = lwh\]The dimensions are all given in the question. Your answer will be in \(\text{ft}^3\), or cubic feet.

Best ResponseYou've already chosen the best response.0Well, I don't think there are any squares, but they are 6 rectangles. Do you know how to calculate the area of a rectangle?

Best ResponseYou've already chosen the best response.0Not quite. Area of a rectangle is \(A=lw\). Now with your box, keep in mind that each pair of opposite surfaces are the same size, i.e. the front and back are the same, the left side and right side are the same, and the top and bottom are the same. Understand?

Best ResponseYou've already chosen the best response.0OK. Using what's given and referring to the sketch, the front and back each have an area of \(l \times h\), the left and right sides each have an area of \(w \times h\), and the top and bottom each have an area of \(l \times w\). Putting all the sides together we get, for the surface area of a rectangular prism,\[SA = 2lw + 2lh + 2wh\]Plug in the values and solve.
