From chap 1 on measurements:


A vertical container with base area measuring 14 cm by 17 cm is being filled with identical pieces of candy, each with a volume of 50 mm^3 and a mass of 0.0200 g. Assume that the volume of the empty spaces between the candy is negligible. If the height of the candies in the container increases at the rate of 0.250 cm/s, at what rate (kg/min) does the mass of the candies in the container increase?
I have no idea if this is a related rates problem or how to start it, does anyone know how to do this? The answer is supposed to be 1.43 kg/min.
