Question

Would a block of mass of 32 g the leisure 3 cm in all directions float or sink in water

Answer 1

A body will float if its density is smaller than the density of water and will sink if its density is bigger than the density of water.

So, you need to calculate the density of the block.

Density = mass / volume

mass = 32 g

volumen = (3cm)^3 = 9 cm^3

=> density = 32 g / 9 cm^3 = 3.55 g/cm^3

Given that the density of water is 1.0 g /cm^3, the density of the block is greater and you conclude it will sink in water.

Answer: the block will sink in water
