Question

The water displacement method is used to determine the volume of_______.

• A. Cubes
• B. cuboids
• C. spheres
• D. irregular objects

Answer 1

The correct option is D

irregular objects

The explanation for the correct option-

1. The irregular shape object is immersed in the water-filled Eureka can.
2. When the object is immersed the water comes out from the spout of the can.
3. This amount of water is stored in a measuring cylinder gives the value of the volume of the irregular-shaped object.
4. Because the volume of the object immersed in the liquid is equal to the volume of the liquid displaced by it.
5. 

The explanation for the incorrect option-

1. Cubes, cuboids, and spheres are regularly shaped objects.
2. Their volume can be determined easily by using the formula.

Hence, D is the correct option.
