Question

Each side of the cube is 8cm and the mass of the cube is 1,536g. What is the density of the cube?

Answer 1

Answer:

The volume is 8^3 = 512 cm^3, and the mass is 1,536g. So the density is 1,536/512 = 0.003 g/cm^3. (Note that the number of significant digits should be 1, as 8 cm being the side length of the cube is in one significant digit.)
