The sixth grade math problem about three-dimensional shape! (quick solution! ! ! ! ! ! ! ! ! ! ! ! ! ! )
The volume of a cuboid = 120 cubic centimeter.

Judging from the meaning of the question:

Cylindrical (the same height as a cuboid), the water level rises 10- 1=9 cm.

Cone (the same height as a cuboid), the water surface rises 1 cm, and overflows 24 cubic cm;

The volume of a cylinder with equal bottom and equal height is three times that of a cone (because the volume of a cone = bottom area × height × 1/3).

So the water level rises by 9 cm, which is equivalent to (water level rises 1 cm, spilling 3 times 24 cubic centimeters).

That is, 3 cm, and the other 24×3=72 cubic centimeters;

So the water level rises by 9-3=6 cm, which is equivalent to 72 cubic centimeters; that is

The water level rises or falls 1cm = 72 ÷ 6 = 12cm3.

The volume of a cuboid = the water level has dropped 10cm =12x10 =120cm3.
