Question

Winnipeg is refilling the pool. How many gallons of water will it take if the pool is 50m by 25m by 1.5m? (1 gallon = 3.786 L )

Answer 1

To get the volume of water in gallons we proceed as follows:
volume=length*width*height
the dimension of the pool is:
50m by 25m by 1.5 m
thus the volume will be:
50×25×1.5
=1,875 m^3
but 1 m^3= 1000 liters
therefore:
1,875 m^3=(1875x1000)=1,875,000 liters
converting the above into gallons we get:
1 gallon= 3.786 L
therefore:
1,875,000 L=1,875,000/3.786 gallons
=495,245.6418 gallons

Answer 2

The volume of the pool is 50m*25m*1.5* = 1875 cubic meters. The standard conversion is 1000 liters per cubic meter. Thus the number of liters in the pool is 1875 m3 * 1000 L/m3 = 1875000 liters.
    1875000L / 3.786L/gal = 495,245 gallons.
