1. The problem statement, all variables and given/known data How big is a ton? That is, what is the volume of something that weighs a ton? To be specific, estimate the diameter of a 1-ton rock, but first make a wild guess: will it be 1ft across, 3ft, or the size of a car? [Hint: Rock has mass per volume about 3 times that of water, which is 1kg per Liter (1000cm) or 62lbs per cubic foot.] 2. Relevant equations 3. The attempt at a solution Well finding the volume of the ton is easy: 3 kg/L = density of rock, so volume would be 333.3 repeating Liters. However, I'm not sure how to answer the original question "how big is a ton?" Anybody have a clear idea what's being asked? This is off a worksheet.
