An object is a regular, rectangular, solid with dimensions of 2 cm by 3cm by 2cm. It has a mass of 24 g. Find its density.

Explanation:

Density can be found using the following formula.

where is the mass and is the volume.

We know the mass is 24 grams. We must find the volume.

Since it is a rectangle, the volume can be found using the following formula.

The length is 2 centimeters, the width is 3 centimeters and the height is 2 centimeters.

Now we know the volume, and can substitute it into the density formula.

The density is 2 grams per cubic centimeter.
