There are 200 paperweights in a box. The mass of each paperweight is 0.085kg. If the mass of the empty box is 560g what is the total mass of the box and the paperweight?
The mass of each paperweight is 0.085 kg, and there are 200 paperweights, so the total mass of the paperweights is 0.085 kg/paperweight * 200 paperweights = 17 kg.
The mass of the empty box is 560 g, which is equal to 0.560 kg.
So the total mass of the box and the paperweights is 17 kg (paperweights) + 0.560 kg (box) = 17.56 kg. Answer: \boxed{17.56}.
