What is the minimum volume of a block of wood(density `=850kg//m^(3))` if it is to hold a `50 kg` woman entirely above the water when she stands on it?

If the density of a block is 981 kg//m^(3) then it shall

A cube of density 250 kg/ m^2 floats in water, then what part of total volume of the cube outside the water?

A cube of density 250 kg/ m^2 floats in water, then what part of total volume of the cube outside the water?

What is the minimum area of a block of ice thick floating on water that will hold up an automobile 1134kg if the thickness of the block of ice is 0.3m ? (Density of ice 910kgm^(-3) )

A block of wood floats on water with 2/5 th of its volume above the water surface. Calculate the density of wood.

A woman of mass 50 kg stands on a wooden block placed over a tank of water. The wooden block is such that the woman is entirely above water. If relative density of wood is 0.85, the volume of the wooden block is:
