Question

To study fluctuations in composition, samples of pumice were taken from 29 loions and cut in the shape of a cube. The length of the edge of one of these cubes is 3.000 centimeters. This cube has a density of 0.230 grams per cubic centimeter. What is the mass of this cube, in grams?

Accepted Answer

The correct answer is 6.21 . It&rsquo;s given that the samples of pumice were cut in the shape of a cube. It's also given that the length of the edge of one of these cubes is 3.000 centimeters. Therefore, the volume of this cube is 3.000 &#160; centimeters 3 , or 27 cubic centimeters. Since the density of this cube is 0.230 grams per cubic centimeter, it follows that the mass of this cube is 0.230 &#160; grams 1 &#160; cubic&#160;centimeter 27 &#160; cubic&#160;centimeters , or 6.21 grams.
