How do you use use water displacement to find the volume of an object?
Example- tAke a measuring cup and a toy car. Let's say you want
to measure the volume of the toy car- fill the measuring cup with
enough water to fully submurge the car but don't put it in yet.
Write down the amount of water in the cup before you put the car
in. Put the car in. Now write down the amount of water in the cup
after fully submerging the car (there will be more). Now subtract
the amount of water before the car from the amount after the car.
That is the volume of the car.
