What is the unified calculation method for the volume of cuboids and cubes?

Measurement steps

1. Measure the length and width of the bottom of the rectangular container and calculate the bottom area.

2. Add an appropriate amount of water to the container, measure the water depth, mark it and record it.

3. Put the stones into the container, measure the rising height of the water surface, and record it.

4. Calculate the volume of the stone.

Knowledge summary:

Water is a liquid. When an object is placed in a container containing water, it can displace part of the volume of water, and the volume of the displaced water is exactly the volume of the object (the object occupies a certain space). As long as we calculate the volume of this part of water, we can indirectly calculate the volume of irregular objects.

1. A rectangular container has a base length of 2 decimeters and a width of 1.5 decimeters. When a potato is placed, the water level rises by 0.2 decimeters. What is the volume of the potato?

2. A rectangular container with a square bottom and a side length of 5 cm contains some water and an iron block. After taking out the iron block, the water level drops by 4 cm. What is the volume of the iron block? If iron weighs 7.8 grams per cubic centimeter, how much does this piece of iron weigh?
