Assignment:
If a solid object such as small brick is submerged in water, it will displace a quantity of water equal to its volume. This fact can be used as a method for measuring volumes.
Suppose that a small brick is put into an aquarium which is the shape of a rectangular solid 1 foot wide, 3 feet long, and 2 feet high. Before the small brick is put into it, the water is 1 foot high. After the small brick is completely submerged, the water is 1 foot 3 inches high. The displaced water is the amount in a rectangular solid 1 foot wide, 3 feet long and 3 inches high. With the tools of arithmetic, calculate the volume of this displaced water. This will be the volume of the small brick.
Provide complete and step by step solution for the question and show calculations and use formulas.
