Surface Area of Prisms and Cylinders Quiz

What is a defining characteristic of a prism?

• It has only triangular faces.

• It has two congruent parallel bases.

• It is always a cube.

• It has circular bases.

How do you calculate the lateral area of a prism?

• Multiply the number of sides by the base length.

• Multiply the perimeter of the base by the height.

• Multiply the base area by the height.
