Question

calculate the density of an object of the volume 3m3 and mass 9.whether this object float o4 sink in water?

Answer 1

Hey!

___________________________

Density= Mass/Volume
d= M/V

Given,

Volume= 3m^3
Mass= 9kg
Density=?

d= 9/3
d= 3 kg/m^3

Object will sink on the water surface as it's density is very less comparatively to water, water has a density of 1000 kg/m^3 at 4°C.

Answer 2

Formula: Density = Mass / Volume

Mass = 5 kg

Volume = 3 m³

Put these values in the formula to find density.

Density of water is 1000 kg/m³.

The object will float if it's density is less than that of water.
