The density, d, of an object is given by the following formula, where m represents the mass of the object and V represents the volume of the object.

Heather was asked to find the density of a brick given the mass in kilograms and the dimensions of the brick in meters. She wrote her answer, 2,400 kilograms per square meter, on the chalkboard. Without even performing the calculations first, Jonathan knew right away that her answer was incorrect. How could he tell there was an error?
The units should be kilograms per cubic meter.

The units should be kilograms per meter.

The units should be kilograms.
