How do you find the volume of a rectangular prism? A rectangular prism is a three dimensional shape with two rectangular parallel bases. The formula for finding the volume of a rectangular prism is base area times the height. ( Ba * h )

Problem 1. Find the volume of a rectangular prism that has a base of 4 units and 7 units, and a height of 5 units.

Step 1. Use the formula for finding volume which equals V= Ba * h

                                                                                           Ba = Base Area

                                                                                           H = height

Step 2. Find the base area of a rectangle Ba = Length x Width

              4* 7 = 28 units

Step 3. Multiply the Ba * height

               28 * 7 = 140 units cubed
