Volume is something that is used to help add what is already measured. Volume can be measured in all different aspects, not only using squared units. This would be false because volume has to ability to be measure in any way that it would want to, but it would only have to complete its purpose, to add what the object is.
(35 + 47 + 42 + x) / 4 = 50 (124 + x) / 4 = 50....multiply both sides by 4, cancelling the 4 on the left side. 124 + x = 50 * 4 124 + x = 200 x = 200 - 124 x = 76 <===
