A pool is 4.57 m long, 3.04 m wide, and 1.83 m deep. If the pool is completely filled with water, what will the weight of the pool be in pounds if 1 Kg=2.2 pounds.
You don't have a density listed; therefore, the mass can't be determined unless you are to look up the density.
I would convert m to cm.
Then volume = length x width x depth in cc.
mass = volume (in cc) x density (in g/cc), solve for mass in grams, convert to kg then to pounds.
