The mass of a packet of wafers is 64 grams. In each packet there are 4 wafers. If the packets must be placed into a box that can hold a maximum of 3.2 kilograms, calculate:

a) The mass of one wafer.

b) The number of wafers that the box can hold.

a. M = 64grams/4wafers = 16 grams = 0.016 kg.

b. Wafers = 4wafers/0.016kg * 3.2kg =
