What is the volume of a rock that has the length of 1.9 cm has the width of 1.5 cm and has the height of 3.8 cm?

It's not often that you find rectangular prism-shaped rocks with these dimensions. Rather, we assume that the rock would fit into a box with the given dimensions, but not actually fill every corner of the box. The maximum possible volume of this rock would be (1.9 cm) (1.5 cm) (3.8 cm) = 10.83 cm^3; the actual volume is most likely less.

the correct answer is 10.83.
