Question

You need to determine the mass of a sample of an element for a science project. The element is in the shape of a rectangular prism with a length of 0.5 centimeters, a width of 0.2 centimeters, and a height of 0.3 centimeters. The density of the element is 2.7 grams per cubic centimeter. Find the mass of the element. (round to the nearest hundredth)

Answer 1

The mass of the prism is approximately 0.08 grams.

Explanation:

The first step to determine the mass, is to calculate the volume of the prism, this can be done using the formula below:

volume = height*length*width

volume = 0.3*0.5*0.2 = 0.03 cm³

Now we need to multiply the volume by the density of the material in order to find it's mass.

mass = volume*density

mass = 0.03*2.7 = 0.081 grams

The mass of the prism is approximately 0.08 grams.
