How Do You Calculate Volume & Density?
The density of an object has many applications including uses as a flotation device or how less dense materials can be used to make everyday items lighter and easier to carry. In order to know the density, first the volume must be calculated, and then the mass. Determine the formula to use for your object. If it is a cylinder, use Pi * radius * radius * height. If it is a rectangular prism, use length * width * height. Measure the dimensions that are needed for the formula. For the cylinder, measure the radius and the height. For a rectangular prism, measure the length, width, and height. Plug in the values measured into the formula to calculate the volume. Place the object on the scale and record its mass. Divide the mass by the volume to get the density.
