This document provides instructions for calculating the surface area and volume of a rectangular prism. It gives the formulas for surface area as SA=2(LxH)+2(HxW)+2(LxW) and volume as V=LENGTH x WIDTH x HEIGHT. An example calculation is shown finding the surface area of a prism with length of 6 cm, height of 4 cm, and width of 5 cm to be 148 cm^2, and its volume to be 120 cm^3.

- 2. Surface Area. To find the surface area of a rectangular prism. You must find out the height, width, and length, after doing that you must follow the formula. The formula is: SA= 2(LxH)+2(HxW)+2(LxW)= your answer. Click to see an example.
- 3. Surface Area Cont. SA= 2(LxH)+2(HxW)+2(LxW)= SA= 2(6x4)+2(4x5)+2(6x5)= SA= 2(24)+2(20)+2(30)= SA= 48 + 40 + 60 = SA= 148 cm 2 The surface area of this rectangular prism is 148 cm 2 Length = 6 cm Height = 4 cm Width = 5 cm
- 4. Volume. To find out volume. You also must have to find out the length, width, and height. After you must follow the formula. The formula is: V=LENGTH x WIDTH x HEIGHT Click to see example.
- 5. Volume Cont. V = 6 x 5 x 4 V = 120 The volume of this rectangular prism is 120. Length = 6 cm Height = 4 cm Width = 5 cm
