A small block has a volume of 4 cubic centimetres. Enter its volume in cubic millimetres.
Correct answer
4000 · Accepted units: millimetres · mm
Explanation
One cubic centimetre is a cube measuring 10 millimetres along every edge, so it contains 10 times 10 times 10 of the tiny cubes. Entering 40 converts only one of the three directions and leaves the block a hundredth of its true size in the new unit.
