Universal Measuring Devices Without Gradations
Measuring cups are everyday instruments used to measure a required amound of liquid for many common tasks such as cooking, ...etc. A measuring cup usually has gradations marked on its sides. In this paper we study measuring devices without gradations but which nevertheless can measure any integral amount, say liters, of liquid up to their full capacity. These devices will be called universal measuringdevices. We determine the largest volume of measuring device with triangular base and obtain one with rectangular base which can measure up to 691 liters.
