Answer:
The weight of the pond contents is 6,643,233.22 lbf
Explanation:
Weight = density × volume × acceleration due to gravity
density = 75.3lbm/ft^3 = 75.3lbm/ft^3 × 0.45359kg/1lbm × (3.2808ft/1m)^3 = 1206.14kg/m^3
volume = length×width×depth = 50m×25m×2m = 2500m^3
acceleration due to gravity = 9.8m/s^2
Weight = 1206.14×2500×9.8 = 29,550,430N = 29,550,430N × 1lbf/4.4482N = 6,643,233.22lbf
