To find the volume of an irregularly shaped wooden piece, a sinker made of steel (relative density = 7.85) having a mass of 157 g was used. If the level of water before and the after immersing the sinker-wood combination are 102 ml and 170 ml, respectively, find the volume of the wooden piece.

If the mass of a solid is 31.2 g, and if the initial and final volume of water level in a graduated cylinder when immersed is 63 mL and 59 ml, respectively, find the density of the solid.

Abhi who is interested in physics measured the volume of an irregular shaped body with concepts given by his physics teacher. When he immersed the given body in water contained in a measuring jar, the level of water is increased from 500 ml to 1500 ml. Find the volume of the body and also find the length of the edge of the cube whose volume is equal to the volume of the given irregular shaped body.
