Question

a company creates tin boxes out of sheet metal. what measure should it use to find out how much sheet metal it needs to make a box that is 6 cm by 4 cm by 18 cm?
○ surface area
○ volume
○ area
○ lateral area

Explanation:

Surface area measures the total area of all the faces of a 3 - D object. Since the company is using sheet metal to make the box (covering all the outer surfaces), surface area is the relevant measure. Volume measures the space inside the box (not relevant for sheet metal amount). Area is a 2 - D measure (not for a 3 - D box). Lateral area does not include the top and bottom faces (but a box has a top and bottom, so we need the total surface area).

Answer:

surface area
