Respuesta :
Given that an object will always displace the same amount of water that its mass is, the ball has a volume of 900cm^3. The displacement method. You get this by multiplying 20 x 15 (the lengths and widths) and multiply it by 3 (the height the water rose) to find the volume.
The volume of the iron ball in the rectangular container that is 20 cm long and 15 cm wide is 900cm³.
How to calculate volume?
The volume of a rectangular cuboid can be calculated by multiplying the length, breadth and the height of the shape.
According to this question, a rectangular container 20 cm long and 15 cm wide contains sone water. When an iron ball was put in the water level rose by 3cm.
Volume of the iron ball = 20cm × 15cm × 3cm
Volume of the iron ball = 900cm³
Therefore, the volume of the iron ball in the rectangular container that is 20 cm long and 15 cm wide is 900cm³.
