Understanding Lateral and Surface Areas of Prisms and Cylinders

What is the main difference between the lateral area and the surface area of a prism?

• Lateral area includes the bases, surface area does not.

• Lateral area is the area of the sides, surface area includes the bases.

• Lateral area is only the area of the bases.

• Lateral area is the total area of the prism.

How is the lateral area of a right prism calculated?

• By adding the perimeter of the base to the height.

• By multiplying the area of the base by the height.

• By adding the areas of all the faces.

• By multiplying the perimeter of the base by the height.

What is the formula for the lateral area of a cylinder?

• 2 times pi times the radius squared.

• Perimeter of the base times the height.

• Circumference of the base times the height.

• Area of the base times the height.

Does the formula for the lateral area of a prism change if the base shape changes?

• No, it becomes the circumference of the base times the height.

• No, it remains the perimeter of the base times the height.

• Yes, it changes with every different base shape.

• Yes, it becomes the area of the base times the height.

In the example of the triangular prism, what are the two different heights used in the surface area calculation?

• The height of the base and the height of the prism.

• The height of the rectangle and the height of the base.

• The height of the triangle and the height of the prism.

• The height of the cylinder and the height of the base.
