Question: 3 what is the formula for finding the volume of a rectangular prism?
Answer: A rectangular prism has three dimensions: length (l), width (w), and height (h). Another way to think about the volume formula is as follows: V = l w h = (l w) h. Since l w is the area of the prism's base, you can think of the volume formula as the area of the base times the height, or V = Bh.
