The density of a stone is 1406 mg/ml and its mass is 9842 mg what is its volume?

You can find the volume by using the formula of density


where d is the density, m is the mass and v is the volume

You have to solve the formula for v like this:


you have the density and the mass so you just have to replace the variables in the formula with the values they are giving you, like this:



The volume of the stone is 7ml
