Two cuboids, the ratio of their length is 3:2, the ratio of their width is 4:3, and the ratio of their height is 5:7? Another cylindrical measuring cup with a circumference of 12.56cm on the ground is filled with water. When a piece of ore is immersed in the cup, the height of water in the cup is 10cm to 15cm. What is the volume of the ore? Formula

Two cuboids, the ratio of their length is 3:2, the ratio of their width is 4:3, and the ratio of their height is 5:7? Another cylindrical measuring cup with a circumference of 12.56cm on the ground is filled with water. When a piece of ore is immersed in the cup, the height of water in the cup is 10cm to 15cm. What is the volume of the ore? Formula

The volume ratio of the two cuboids: (3 × 4 × 5): (2 × 3 × 7) = 10:7
Bottom radius of cylindrical measuring cup: 12.56 △ 2 △ 3.14 = 2cm
The volume of this ore is 3.14 × 2 × 2 × (15-10) = 62.8 cubic centimeter
