An amazing formula from ancient mathematics was used by the Egyptians to find the volume of the frustum of a square pyramid, as shown in the figure. Its volume is given by v=h(a² + ab + +b²), where b is the length of the base, a is the length of the top, and h is the height. b a b a. When a pyramid was partially completed to a height h of 198 ft, b was 759 ft, and a was 318 ft. Calculate its volume at this stage of construction. The volume ist. (Round to the nearest integer as needed.)
