Σελίδα 602 - V9 x 25 sq. ft. = 15 sq. ft. NOTE. — The mean proportional between two numbers is equal to the square root of their product. 13. Find the volume of the frustum of a square pyramid, its upper base containing 64 square inches, and its lower base 196 square inches, its altitude being 18 inches. 1294. Note that the mean proportional between 64 and 196 is 8 x 14, or 112. Since each is multiplied by one-third of the altitude, the operation is shortened by adding together the three areas, 64, 196, and...
