7. A stone bridge has three equal semicircular arches resting on four equal rectangular piers. The radius of each arch is R, the o dimensions of the piers L, W, H, while the distance from the top of each pier to the top of the bridge is D. If L- 50 ft., W = 5 ft., H = 10 ft., R = 6 ft., D = 12 ft., find the volume of material used in building the bridge.
