Question

mass (kg) = 350 and volume (m3) density =?

Answer 1

p=m/v
i.e.,
density =mass/volume
=350kg/m^3

Answer 2

Pressure=mass/volume

i.e. density =mass/volume

=350kg/m^3

Mass is the amount of matter present in a body.

Pressure is the force per unit area.

It is the quantity of three-dimensional object enclosed by a closed surface, the space that a substance or shape occupies or contain.
