The units of measurement in a data table should be shown at the top of each column (headings containing the name of the variable and the unit should be in parentheses)
Explanation:
The units of measurement must be in the headings of each column, considering that all values of each column correspond to that unit. It should be in the same units system, whether it's international or English system.
Since its volume you do what it says 55 cm x 100 cm x 80cm and do 100 x 50 which is 5,000. then 5,000 x 80 which is 40,000. sorry i cant show work on here.
