Problem- A green roof is designed to hold up to 0.8 inches of precipitation before water starts to runoff. For a building with a greenroof that is 760x650 feet, determine the weight of water ( in lbs) that would be on the roof when the greenroof is saturated. Liquid water is 62.4 pounds/cu-foot
Please perform what you can and illustrate your work so I can follow. Thanks
