Surface Areas of Prisms and Cylinders
To find the surface area of a prism, you need to calculate the sum of the areas of all the faces of the prism. The formula for the surface area of a prism is:
Surface Area = 2lw + 2lh + 2wh
where l is the length, w is the width, and h is the height of the prism.
To find the surface area of a cylinder, you need to calculate the sum of the areas of the two circular bases and the lateral surface area. The formula for the surface area of a cylinder is:
Surface Area = 2πr^2 + 2πrh
where r is the radius and h is the height of the cylinder.
