Surface Area of Prisms
Prisms are three-dimensional shapes with two parallel faces called bases and a number of rectangular faces called lateral faces. The surface area of a prism is the sum of the areas of its bases and lateral faces.
Calculating Surface Area of Prisms
The formula for calculating the surface area of a prism is:“`Surface Area = 2(Base Area) + (Lateral Surface Area)“`where:* Base Area is the area of one of the bases
Lateral Surface Area is the sum of the areas of the lateral faces
Examples of Prisms and Their Surface Areas
Here are some examples of different types of prisms and their surface areas:*
-*Rectangular prism
A prism with rectangular bases and rectangular lateral faces. Surface Area = 2(lw + lh + wh)
-
-*Triangular prism
A prism with triangular bases and triangular lateral faces. Surface Area = 2(1/2bh + bl + bh)
-*Pentagonal prism
A prism with pentagonal bases and rectangular lateral faces. Surface Area = 2(1/2ap + as + 5sl)
Table of Surface Areas of Prisms
| Prism Type | Base Area | Lateral Surface Area | Surface Area ||—|—|—|—|| Rectangular prism | lw | 2(lh + wh) | 2(lw + lh + wh) || Triangular prism | 1/2bh | 3bl | 2(1/2bh + bl + bh) || Pentagonal prism | 1/2ap | 5sl | 2(1/2ap + as + 5sl) |
