What is the total force (newtons) on the dam face if the water level from Lake Mead (holding basin for Hoover?

Hoover Dam was built in the 1930s to provide electricity for the southwest U.S. and to prevent the wild Colorado River from flooding. Hoover Dam is about 380 m wide and is about 221 m high. ume that Hoover Dam can be approximated by slab geometry with a width of 380 m (W). What is the total force (newtons) on the dam face if the water level from Lake Mead (holding basin for Hoover Dam) is 200 m (D)? ume the density of water in Lake Mead is 1000 kg/m3
