During heavy rain, a section of a mountainside measuring 3.0 km wide horizontally, 0.67 km up along the slope, and 2.5 m deep slips into a valley in a mud slide. Assume that the mud ends up uniformly distributed over a surface area of the valley measuring 0.59 km x 0.59 km and that the mass of a cubic meter of mud is 1900 kg. What is the mass of the mud sitting above a 3.8 m² area of the valley floor? Number i Units
