What is lateral surface area?

• The area of all of the sides (including bases or top and bottom).

• The area of only the sides (not including the bases or top and bottom).

• The perimeter of the base.

• The area of the base.

What is total surface area?

• The area of all of the sides (including bases or top and bottom).

• The area of only the sides (not including the bases or top and bottom).

• The perimeter of the base.

• The area of the base.

What is the difference between lateral and total surface area?

• Total surface area solves for perimeter of all the sides where lateral solves for area.

• Total surface area is the sum of the area of all the sides where lateral surface area is the sum of the area of only the sides. (Not including the bases or top and bottom).

• Total surface area can only be used for prisms and lateral surface area can only be used for cylinders and cones.

• None of the above.
