Awooden cube has an edge length of 6 centimeters and a mass of 137.8 grams. determine the density of the cube, to the nearest thousandth.

The mathematical definition of density is the mass divided by the volume. In this case the volume of the cube is 6 x 6 x 6 = 216 cubic centimetres. Dividing a mass of 137.8g by a volume of 216 cubic cm yields a density of 0.6379 grams per cubic cm. To the nearest thousandth we need to round to 4 decimal places and so have a final answer of 0.638 grams per cubic cm.

Sorry can't answer that question
