Answer:
607.6g
Step-by-step explanation:
Assume each mark on the scale represented 1 g. That is 1 cm = 1g
To estimate how much a sheet of paper would mass a sheet of paper is 28 cm by 21.7 cm, first calculate the area.
Area = 28 × 21.7 = 607.6 cm^2
Mass = 607.6 × 1g = 607.6 g
Therefore, the estimation will be 607.6g
