The volume v of a pyramid with a square base with side length s and height h is upper v equals one third s squared hv= 1 3s2h. solved forâ s, this formula gives s equals startroot startfraction 3 upper v over h endfraction endroots= 3v h. a pyramid has a volume of approximately 7 comma 700 comma 0007,700,000 cubic meters. find the length of the side of the pyramid if its height is approximately 148148 meters.
