A square piece of paper measuring 4.8 inches on a side is weighed and found to have a mass of 1.5 grams. How many pounds would exactly 500. sheets of this paper weigh, given that each page measures 21.50 cm by 27.73 cm?
area square piece = 4.8 in*2.54 cm/in x 4.8 in x 2.54 cm/in = ? cm^2 and mass = 1.5 g
area large piece = 27.73 cm x 21.50 cm = ? cm^2
mass 1 sheet large paper =
1.5 g x (area large sheet/area small sheet) = ? g
x 500 for 500 sheets paper.
mass 500 sheets/454 = lbs for 500 sheets large paper.
