Surface Area of Prisms

Front

What is surface area?

Back

The sum of all the areas of all the shapes that cover the object.

Front

What is a prism?

Back

A solid shape with two identical ends and flat sides.

Front

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

Back

Add the areas of all six faces: SA = 2lw + 2lh + 2wh.

Front

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

Back

SA = 2πr(h + r), where r is the radius and h is the height.

Front

What is the difference between surface area and volume?

Back

Surface area measures the total area of the surface, while volume measures the space inside the solid.

Front

What units are used to measure surface area?

Back

Square units, such as cm², m², or in².

Front

Find the surface area of a cube with side length 4 cm.

Back

SA = 6s² = 6(4)² = 96 cm².

Front

What is the surface area of a triangular prism?

Back

SA = base area + lateral area, where lateral area is the sum of the areas of the three rectangular sides.

Front

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

Back

Multiply the perimeter of the base by the height of the prism.

Front

What is the surface area of a sphere?

Back

SA = 4πr², where r is the radius.
