What is the formula for lateral surface area?

• Lateral surface area = perimeter of the base / height

• Lateral surface area = 2 x base area + perimeter of base x height

• Lateral surface area = perimeter of the base x height

• Lateral surface area = base area x height

Why do we multiply the area of one base by 2 to find the area of the bases?

• It's a mistake; we should not multiply by 2

• To double the total surface area

• To account for the lateral surface area

• Because the prism has two bases
