Answer 1

Explanation:

Find the mass of given irregular solid using a physical balance. Let it be M.

Find the volume of given irregular solid using dispalcement method in a measuring jar. Let it be V.

density = Mass/Volume = M/V.

Answer 2

Explanation:

• Take a piece of brass, a measuring cylinder, fine thread of sufficient length and some water.
• Place a measuring cylinder on a flat horizontal surface and fill it partially with water.
• Note the reading of the water level very carefully.
• Now tie the piece of brass with a thread and dip it completely into water.
• We see that the level of water rises.
• Note the reading of the new water level.
• The density of irregular solid = 20^ 3
