Find in liters the capacity of a cubic box whose external edge length is cm given that the material of which it is made has a thickness of cm.
Step 1: Find the internal edge length of the box.
Subtract the thickness of the material on each side from the external edge length.
Step 2: Find the volume of the box in cubic centimetres using the internal edge length.
Use the formula for the volume of a cube.
Step 3: Convert the units to litres.
is equivalent to , so divide the number of cubic centimetres by to convert to litres.
