cm. 36 MP4056 Volume of Rectangular Prisms The volume of a rectangular prism is found by multiplying length, width, and height. Another way to think of it is finding the area of the base (length x width) and multiplying by height. Volume is measured in cubic units (units3). OR Volume = length x width x height Volume = (area of base) x height Find the missing measures in the chart below. length width height 1. 10 cm 5 cm 8 cm 2. 20 m 10 m 15 m 3. 14 in 6 in 9 in 4. 3 ft 4
