Question

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 1 ft across, 3 feet, or the size of a car? (Hint: Rock has mass er volume about three times that of water, which is 1 kg per liter(10^3cm^3) or 62lb per cubic foot) ...?

Answer 1

Short ton is equal to 2000 lb. A metric tonne is equal to 1000 kilograms.

To get the volume of a rock you should divide the mass (1000 kg) by the density. Assume the density is three times of water. You can assume the rock is a sphere or cube to get the approximate dimension from the volume. 

The density of water is 1000 kg / m^3
