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

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
