a student needs to find the density of a cube . each side of the cube measures 3 cm and the mass of the cube 12g.
Sure thing! I remember that lesson!
Density is found by taking the mass and dividing by the volume.
Since we are dealing with a cube, it is easy to find the volume. Volume of a cube is s^3, where "s" is the side length. So we take 3 cm to the power of 3, or 3^3. =27
Now we just take the mass, 12g, and divide by the volume, 27 cm^3.
Density = 12/27 = 4/9. Don't forget the units!!!
4 g________9 cm^3
