There is a cuboid glass tank with a volume of 32.4 cubic decimeters. Its length is 80 cm and its width is 45 cm. What is the height of this glass tank fast

There is a cuboid glass tank with a volume of 32.4 cubic decimeters. Its length is 80 cm and its width is 45 cm. What is the height of this glass tank fast

32.4 cubic decimeter = 32400 cubic centimeter
Height of glass jar
32400 ÷ (80 × 45) = 9 (CM)

The bottom area of a cuboid is 16 square decimeters, the height of the water is 6 decimeters, and the volume of the iron block is 18 cubic decimeters. What is the original cuboid volume

16×6＝96dm³
96＋18＝108dm³
108÷16＝6.75dm
At this time, the water surface is 6.75 decimeters high

A cuboid container, the bottom area of 20 square meters, into the water height of 6 decimeters, into the volume of 18 cubic decimeters of iron, then how high is the water

If all the iron blocks are submerged in the water, the water surface will rise
0.018 m3 / 20 m2 = 0.0009 M = 0.9 mm
At this time, the total height of water surface: 600mm + 0.9mm = 600.9mm
If not all the iron blocks are submerged in the water, the above calculation method shall be used according to the volume of iron blocks submerged in the water
