The cuboid bucket is 5 decimeters long, 3 decimeters wide and 0.6 meters high. When it is filled with water, how deep is the water when it is poured into a cube container with an edge length of 6 decimeters

The cuboid bucket is 5 decimeters long, 3 decimeters wide and 0.6 meters high. When it is filled with water, how deep is the water when it is poured into a cube container with an edge length of 6 decimeters

H = (0.5 * 0.3 * 0.6) / (0.6 * 0.6) = 0.25m = 2.5decimeter

Cuboid bucket, the bottom is a cube, the side area is 100 square decimeters, the height is 40 cm, how many kilograms of water can this bucket hold?
One cubic decimeter of water has a mass of one kilogram

40 cm = 4 decimeters
Bottom area 100 / 4 = 25 square decimeters
Volume = 25 × 4 = 100 cubic decimeter
It can hold 100 kg of water

A square empty water tank, the bottom area is 16 square decimeters, now put a square iron block with the edge length of 2 decimeters into the bucket, at least how many liters of water to pour,
Only when the water level is equal to the top of the iron block can the iron block be submerged

The height of the water surface is 2 decimeters
Total volume of water and cube: 16 × 2 = 32 (cubic decimeter)
Volume of cube: 2 × 2 × 2 = 8 (cubic decimeter)
Volume of water poured: 32-8 = 24 (cubic decimeter) = 24 liters
Therefore, at least 24 liters of water must be poured to submerge the iron block
