Chapter Surface Area of Triangular Prisms

15. Surface Areas of Triangular Prisms
Objective: To find the surface area of triangular prisms.

16. Surface Areas of Triangular Prisms
The surface area (SA) of a three dimensional figure is the outer face or exterior boundary of the figure.

17. Surface Areas of Rectangular Prisms
There are three formulas to find the surface area of a triangular prism. Right Triangular Prism Formula Non-Right Triangular Prism Formula Universal Prism Formula

18. Surface Areas of Rectangular Prisms
We will be using the Universal Prism Formula. SA = 2B + ph

19. Surface Areas of Rectangular Prisms
Find the SA of the triangular prism using SA = 2B + hp To Find the SA of a triangular prism. Step 1 – Find the area of the base.

20. Surface Areas of Rectangular Prisms
Find the SA of the triangular prism using SA = 2B + hp B = 2 ·3 2 = 3 The base on a triangular prism will always be a triangle. To Find the SA of a triangular prism. Step 1 – Find the area of the base.

21. Surface Areas of Rectangular Prisms
Find the SA of the triangular prism using SA = 2B + hp B = 3 To Find the SA of a triangular prism. Step 2 – Find the perimeter of the base.

22. Surface Areas of Rectangular Prisms
Find the SA of the triangular prism using SA = 2B + hp B = 3 p = = 8.6 To Find the SA of a triangular prism. Step 2 – Find the perimeter of the base.

23. Surface Areas of Rectangular Prisms
Find the SA of the triangular prism using SA = 2B + hp B = 3 p = 8.6 To Find the SA of a triangular prism. Step 3 – Find the height.

24. Surface Areas of Rectangular Prisms
Find the SA of the triangular prism using SA = 2B + hp B = 3 p = 8.6 h = 4 To Find the SA of a triangular prism. Step 3 – Find the height.

25. Surface Areas of Rectangular Prisms
Find the SA of the triangular prism using SA = 2B + hp B = 3, p = 8.6 , h = 4 To Find the SA of a triangular prism. Step 4 – Substitute the measurements in for the correct variables and solve.

26. Surface Areas of Rectangular Prisms
Find the SA of the triangular prism using SA = 2B + hp B = 3, p = 8.6 , h = 4 SA = 2 · · 8.6 SA = = 40.4 cm² To Find the SA of a triangular prism. Step 4 – Substitute the measurements in for the correct variables and solve.

27. Surface Areas of Triangular Prisms
Another way to find the SA is to deconstruct the shape into a net. The surface area (SA) of a prism is the sum of all the areas of it’s faces.

28. Surface Areas of Triangular Prisms
Find the SA of the triangular prism. With a net, compute the area if it was a composite figure.
