One student multiplies the edge lengths of a right rectangular prism to get the a volume of 78 cubic units. What is one way to check that the volume is correct?

One way to check that the volume is correct is to calculate the volume of the right rectangular prism using the formula V = l x w x h, where l is the length, w is the width, and h is the height of the prism. Once you have found the volume using the correct edge lengths, compare it to the given volume of 78 cubic units. If they match, then the calculated volume using the edge lengths provided by the student is correct.
