Front

How do you find the surface area of a rectangular prism?

Back

Add the areas of all six rectangular faces.

Front

What is the formula for the surface area of a cube?

Back

Surface Area = 6 * (side length)^2.

Front

What is the total surface area of a rectangular prism with dimensions 4 inches, 3 inches, and 2 inches?

Back

Total Surface Area = 2(4*3 + 4*2 + 3*2) = 2(12 + 8 + 6) = 2(26) = 52 square inches.

What is the difference between a prism and a pyramid?

Back

A prism has two parallel bases and rectangular sides, while a pyramid has one base and triangular sides that meet at a point.

Front

What is the surface area of a triangular prism with a base area of 12 square inches and a height of 5 inches?

Back

Surface Area = (Base Area * 2) + (Perimeter of Base * Height).
