How to find the volume of a rectangular prism?

-- Measure the length.
-- Measure the width.
-- Measure the height.

(Note:  If someone told you what any of these is, then
you don't need to measure it.)

Now you have three numbers.

-- Multiply any two of them.
-- Multiply the product by the third one.

-- The last product is the volume of the rectangular prism.

The answer would be 484
