a typical backyard swimming pool holds 150 yd^3 of water. what is the mass in pounds of the water?

Answer 1

What is the density of water in pounds/cubic foot? I think the conversion factor for cubic yards to cubic feet is 27 cubic feet = 1 cubic yard.
Convert 150 yd^3 to cubic feet.
Then mass = volume x density.
Or if you can find the density of water in pounds/yd^3, then
150 x that number = mass in pounds.

Answer 2

2.5 *10^5 lbs
