or:In general, volume varies as the cube of size. Half the volume corresponds to 0.7937 times the size. That is to say (0.7937)^3 = 1/2. So you multiply the given lengths by 0.7937.

or:The volume v of the rectangular prism is obviously v = 4 * 7 * 7 = 196.You are looking for a prism of similar shape with half the volume:v / 2 = (4 * 7 * 7) / 2 = 196 / 2 = 98.As the condition is \"similar shape\
