. If you have a swimming pool that is 8.75 meters long, 4.25 meters wide, and 2.75 meters deep, how many kilograms of water would you have in a pool?
Hint: 1 cubic centimeter of water weighs 1 gram.

First figure out the volume of the pool.

Volume = Length * Width * Height

8.75 meters * 4.25 meters * 2.75 meters = 102.265625 cubic meters

You list the density in grams per cubic centimeter, so we need to convert the volume to cubic centimeters.

102.265625 cubic meter = 102265625 cubic centimeter

Now we know the volume, multiply by the density.

102265625 cubic centimeter * 1 gram/cubic centimeter = 102265625 grams

Thats an awkward number, we can convert to kilograms.

102265625 gram = 102265.625 kilogram

or metric tons

102265625 gram = 102.265625 metric ton
