Question

The largest part of landfills is made up of newspapers. A 30.48 cm stack of newspapers weighs about 15.87 kg. How many grams does this stack of newspapers weigh?

Answer 1

I think the answer is 15870

Answer 2

First find how many grams are in 15.87kg and how many meters are in 30.48cm

15.87kg x 1000g/kg = 15, 870g
30.49cm x 1m/100cm = 0.3049m



Then, set up a proportion.

0.3049m/15, 870g = 1m/x g

Cross multiply to get..
0.3049x = 15, 870

Divide for x and there you are.Source(s):Myself.1004 · 8 years ago
