Whats the total area of covered box with a length of 4ft a width oc 3ft and height of 6 ft

The total area of a box is the sum of all the area of the faces it has. It is also called the surface area. The area of one face of a rectangular box is equal to the product of its length and width. So, the total area would be:

SA = 2lw + 2wh + 2lh

SA = 2 (4) (3) + 2 (3) (6) + 2 (4) (6)

SA = 108 ft^2
