Whats the area of a cardboard In one carton if the length is 9 inches height is 9inches width is 4 inches and is 240 ml as well as also in a 946 ml container and a 1.89 L container?

Assuming that the cardboard forms a regular rectangle, therefore the area of the cardboard is simply taken to be the product of length and width. Therefore:

A = l w

A = (9 inches) * (4 inches)

A = 36 square inches = 36 inches^2
