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)

This is a terrible question. A ton is a measure of mass, not volume or density. A short ton is 2000 lb. A metric tonne is 1000 kilograms. Taking the rock to be spherical, the volume is expressed as \[{4 \over 3} \pi r^3\]With the given density value, we can say that\[m = \rho \cdot {4 \over 3} \pi \cdot r^3\]where \(\rho\) is the density.

one cubic meter of water equals 1 tonne \[1m^3 \times H_2O\]|dw:1327711997113:dw| 1 ton is about 1.1tonne

Sorry, the book also says assume the rock is spherical NOT cubic.

If its a sphere you want then eashmore's answer provides you with the necessary formula. Just make sure you keep your units straight.
