Hey guys , please kinda show me the solution for this problem .
The Answer is 77/48 ft.
Two rectangular water tanks with tops on the same level are connected by a pipe through their bottoms. The base of one is 6 in. higher than that of the other. Their dimensions are 4 by 5 by 2 1/2 ft, and 4 by 7 by 3 ft., respectively. How deep is the water in the larger tank when the water they contain equals half their combined capacity, if the 2 1/2 ft. and 3 ft. edges are vertical?
