Using data and observations, answer the following questions. Did it seem, that the mass of each 1 cm2 of paper would have the same mass? Explain your response.
How many pieces of 1 cm2 paper would it take to reach the fifth mark on the scale? Show your rationale.
Assume each mark on the scale represented 1 g. Estimate how much a sheet of paper would mass. A sheet of paper is 28 cm by 21.7 cm.
The actual mass of a sheet of copy paper is 4.5 g. What must be the actual mass of a 1 cm2 piece of copy paper? Show your calculations.
