3] a student has 500 identical, rectangular sheets of paper. the mass of 1.0 square m of the paper is 0.080kg. a] using a meter rule, she measures the length of one sheet of paper and it's width. the length is 0.300m and the width is 0.210m. [i] calculate the mass of one sheet of paper. [ii] the student makes a single pile of the 500 sheets of paper. with a meter rule, she measures the height of the pile. the height of the pile is 0.048m calculate the density of the paper. b] a second student has only 5 sheets of the same type of paper. suggest how this student determines the density of the paper to a similar accuracy. additional apparatus may be used.
