A solid piece of lead has a mass of 29.89 g and a volume of 2.67 cm³. From these data, calculate the density of lead in SI units (kilograms per cubic meter). ер 1 The density of lead is 1.13 × 10“ kg/m³, so we should expect our calculated value to be close to this value. The density of water is 1.00 × 103 kg/m³, so we see that lead is about 11 times denser than water, which agrees with our experience that lead sinks.

Units and Dimensions

These are generally defined as the terms which precede or describes the dimensions further. These are also further divided into two parts namely fundamental units and the derived units.
