A vertical containery with base area measuring 14.0 cm by 17.0 cm is being filled with identical pieces of candy, each witha volume of 49.0 mm3 and a mass of 0.0210 g. Assume that the volume of the empty spaces between the candes is negligible. If the height of the candes in the container increases at the rate of 0.270 cm/s, at what rate (kilograms per minute) does the mass of the candies in the container increase?
