Answer 1

The units of quantities other than those measured in fundamental units can be expressed in the terms of fundamental units and they are called derived units. Thus, derived units or which can be expressed in terms of the fundamental units. For example:

(i) For the measurement of area, we need to measure length and breadth in the unit of length and then express area in a unit which is length*length or (length)^2.

(ii) Volume is expressed in a uni which is length*length*length or (length)^3.

(iii)The unit speed of a moving body is obtained by dividing the unit of distance such as, length by unit time and it can be expressed in the terms of the units of length and time.
