Is a coffee mug 300 milliliters or 3 liters?
We can find the answer mathematically as follows:The average coffee mug is 3.5 inches in diameter and 4-5 inches tall, this gives it a maximum capacity to hold 48 cubic inches of liquid (5 x (PI x 3.52)). Next let's see which of these two quantities will fit in this mug. First, let's try 3 liters. Since, 1 liter equals 61 cubic inches, three liters will takes up 183 cubic inches - that's enough to fill almost four of our coffee mugs. That leaves us with our correct answer of 300 milliliters which equals 18.3 cubic inches, which is well within the maximum capacity of an average coffee mug. So, 300 milliliters is a possible capacity for a coffee mug.We could also solve this problem analytically. Since, we know that most soda comes in a two-liter bottle, we can compare the liquid in one and a half of those bottles with the size of a coffee mug. It is obvious from holding the two side-by-side that an average coffee mug could never hold three liters. This way we can deductively single out the correct answer: 300 milliliters.
