Answer: 60 cm³
Step-by-step explanation: To calculate the volume, all the mesurements MUST be in the same unit.
As a requirement of the problems, we need to change the length to cm. For the length, we have that 10 mm = 1 cm, so 100 mm = 10 cm. Note that that is linear.
Volume (V) = L x E x H = 10 cm x 3 cm x 2 cm = 60 cm³
The index of the Volume unit is very important.
