Surface Area of Prisms

The sum of all the areas of all the shapes that cover the solid figure.

Triangular prism.

Add the areas of all the faces of the prism.

Surface Area = 2(lw + lh + wh), where l is length, w is width, and h is height.

Surface Area = 6a^2, where a is the length of a side of the cube.

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

Surface Area = 4πr^2, where r is the radius.

The sum of the areas of all its faces, including the bases.

Area = 1/2 * base * height.

Surface Area = 2 * base area + perimeter of base * height.
