What is the density of an object if it's mass is 15 g and it's volume is 3cm3

The density of object is 5 g / cm³.

Explanation:

Density:

Density of an object is equal to its mass divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL, kg/L

Formula:

D=m/v

D = density

m=mass

V=volume

Symbol:

The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.

Given dа ta:

mass = 15 g

volume = 3 cm³

density = ?

Solution:

d = m / v

d = 15 g/3 cm³

d = 5 g / cm³

so the density of object is 5 g / cm³.
