A square metal plate has a surface area of $1.5\text{ m}^2$. What is this area expressed in square centimetres ($\text{cm}^2$)?

To determine the volume of 50 small identical glass beads, a student pours $30\text{ cm}^3$ of water into a measuring cylinder and then adds all the beads. The water level rises to $42\text{ cm}^3$. What is the volume of a single glass bead?

Why does ice float on liquid water, whereas most other substances sink when they freeze?

A uniform block of material has a mass of $450\text{ g}$ and a volume of $150\text{ cm}^3$. If this block is cut into two unequal pieces, the density of the smaller piece will be:

A block of copper has a density of $8960\text{ kg m}^{-3}$. If the block has a total mass of $448\text{ kg}$, calculate the volume of the block.
