1 A student measures the mass M of 500 sheets of paper.
The student then measures the length L and width W of one sheet of paper.
The values of M, L and W are recorded in the table.
Quantity Measurement
M 2520 g
L (29.7 ± 0.1) cm
W (21.0 ± 0.1) cm
(a) State the measuring instrument used to measure L and W.

(b)
(i) Calculate the area A of one sheet of paper.
Give your answer to an appropriate number of significant figures.
A = ................................................... cm2 [2]
(ii) Calculate the pressure p that the 500 sheets of paper exert on a bench.
p = ............................................. N cm–2 [2]

(c) The density of this paper is 1.2 g cm–3.
Calculate the thickness t of one sheet of paper.
volume
Use the formula: thickness =
area
t = .................................................... cm [2]
(d) Explain how the student can determine the thickness of one sheet of paper experimentally.
