Density equals the mass of the substance divided by its volume; D = m/v. Objects with the same volume but different mass have different densities. Students will observe a copper and an aluminum cube ...

Volume is a measure of the amount of space an object takes up. It is always in three dimensions. To find the volume of an objects like a cube or a box, measure the length × width × height. If measured ...

Thus, the surface-to-volume ratio for a cube is: Surface-to-Volume Ratio (Cube) = 6L 2 / L 3 = 6/L. As the side length L decreases, the surface-to-volume ratio increases inversely proportionally. This ...

Japanese toymaker MegaHouse has unveiled a miniature Rubik’s Cube — one so tiny that you might need a pair of tweezers to solve it. Each face of the cube, which is made from aluminum, measures ...
