The edge of a cube glass container is 2 decimeters long, and the water depth in the container is 12 cm What's the volume of stone in cubic centimeter?
15-12 = 3cm
3×20×20=1200cm²
How many? The edge length of a cube glass container is 2 decimeters. Pour 5 liters of water into the container, and then put a stone into the water. At this time, the water depth in the container is 15 cm. What is the volume of the stone
Original height of water surface = 5 ÷ (2 × 2) = 1.25 decimeter = 12.5 cm
After the stone is put into the water, the water surface rises = 15-12.5 = 2.5 cm = 0.25 decimeter
The volume of stone = 2 × 2 × 0.25 = 1 cubic decimeter
In a 5 cm long, 4 decimeter wide cuboid glass jar, put a 20 cm long square iron block, and the water depth is 25 cm
When the block is taken out of the cylinder, how high is the water surface in the cylinder?
The length is 5 decimeters
The actual volume of water is 50 × 40 × 25-20 × 20 × 20 = 42000
The bottom area of the cylinder is 50 × 40 = 2000
The height of water is the quotient of the two: 42000 / 2000 = 21cm
