The total weight is 1550g. The net weight is 1500g. The weight of one sheet of paper is 3g.
Work Step by Step
Move the decimal to convert mg to g. $3000mg=3g$ Multiply by the number of sheets to find the net weight. $3g\times500=1500g$ Add the weight of the packaging to find the total weight. $1500g+50g=1550g$
