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.

607.6g

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

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
