A cuboid glass fish tank is 6 decimeters long and 5 decimeters wide. There is water in the tank, and the water surface is 1 decimeter away from the upper edge of the tank. If a square iron block with 3 decimeters long is put into the tank, will the water overflow? Why?

A cuboid glass fish tank is 6 decimeters long and 5 decimeters wide. There is water in the tank, and the water surface is 1 decimeter away from the upper edge of the tank. If a square iron block with 3 decimeters long is put into the tank, will the water overflow? Why?

Fish tank bottom area: 6X5 = 30 square decimeters,
30x1 = 30 cubic decimeter,
3x3x3 = 27 cubic decimeters,
30＞27
A: because 30 > 27

A glass fish tank is 1.2 meters long, 0.4 meters wide, 0.8 meters high, and 0.5 meters deep. How many decimeters is the water surface from the mouth of the fish tank behind a rockery with a volume of 96 centimeters

1.2m＝12dm 0.4m＝4dm 0.5m ＝5dm
12 × 4 × 5 = 240 (cubic decimeter)
240-96 = 144 (cubic decimeter)
144÷（12×4）＝39dm
By the way, it's a mathematical problem, not flowers, birds, fish and insects
