Explain two ways to find volume of a plastic cube?
1. Measure the length of one of the sides and cube it (ie multiply the length by the length by the length) 2. Get a bowl with enough water to cover the cube; mark the level of the water; submerge the cube in the water and mark the new level of the water. The volume of the cube is the volume between the two marks - this can be measured by removing the cube and using a measuring jug to measure the amount of water that is needed to be added to raise the water from the first mark to the second mark.

How many btu's are needed to raise the temperature of a 30000 gal pool from 65 to 80 degrees Fahrenheit?
A US gallon of water is about 8.4 lb, so 30,000 galls is 252,000 lb. One BTU is the heat to raise one pound of water by one degF, so BTU's in your example are 252,000 x 15 = 3,780,000 BTU.
How many watts produce to raise the temp of 1 cubic meter water to 1 degree centgrade?
That depends how fast you want to do this. Please note that "watt" is not a unit of energy, it's a unit of power (energy per time unit).
