Question

_____ is used to calculate volume of an irregular object.

Answer 1

1. An object that does not have regular shape is called irregular object, for example stone, screws etc.
2. Volume of irregular objects cant be determined using direct methods as these objects have irregular height, breadth and length,
3. Indirect methods are used to find volume of objects by dropping these objects into water and noting down the volume of water displaced.
4. Apparatus like graduated beaker and cylinder are used to find the volume.

Hence graduated beaker, cylinder is used to calculate volume of an irregular object.
