Surface Area is the area of the outside of a shape. Im going to show you how to get the surface area of a rectangular prism.

First you need to make a net. The net shows the front, the back, the top, the bottom, and the sides. But the front and the back are the same area, the top and bottom are the same, and so are the sides.

Once you have your net. You use the simple formula for adding the measuerments. (LxW)(WxH)(HxL) Since the net is flat, you have to square the number.

Well after you use the formulas with the measurements, you can add it up and get the surface area. You can use the example I gave you to help better understand.

Volume:

Volume is how much the entire shape takes up. To get the volume of a rectangular prism, you multiply the length (L), width (W), and height (H). That will get you the volume of the entire shape. The answer, is always cubed or in 3. ex. 18 cubic(3) centimeters.
