25 A sheet of A4 card weighs \(1.19 \times 10^{-2}\) kg.
(a) Work out the weight of 500 sheets of the A4 card. [2]
(b) Card is classified using \(W\), the weight in grams per square metre (gsm).\[W = \frac{\text{weight in grams}}{\text{area in square metres}}\]
A sheet of A4 card is a rectangle that is 21 cm by 29.7 cm.
Calculate \(W\) for this A4 card. [4]
