    |dw:1439823750647:dw| The box is in the shape of a rectangular prism. You are asked to find the volume of the box. 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.

    @halia according to the dimensions given, your decimal is in the wrong place.

    Don't guess. Calculate \(40 \times 28 \times 6.7\)

    Sure. How many surfaces does the box have?

    Great. What shape are the surfaces?

    @ospreytriple they are squares and rectangles

    Well, I don't think there are any squares, but they are 6 rectangles. Do you know how to calculate the area of a rectangle?

    Um is it A=l*w*h ?

    Not 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?

    OK. 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.
