The formula for density is d = m/v.
d = density
m = mass
v = volume
The volume of the rock is 15 cubic centimeters.
The mass of the rock is 45 grams.
Now just plug these into the formula and solve.
d = 45/15.
45/15 = 3.
The density of the rock is 3 grams per cubic centimeters.
Mass of the rock = 45 g
Volume of the rock = 15 cubic cm
Density = Mass / Volume
By putting the respected values, we get
Density = 45 g / 15 cubic cm = 3 gram/cubic centimeter
Density of the rock is 3 gram/cubic centimeter.
