A triangular prism is a three-dimensional shape that has two parallel triangular bases and three rectangular sides. The volume of a prism is found by multiplying the area of its base by its height (V = Bh). The surface area is the sum of the areas of all its faces.
1. Identify the following parts of a triangular prism:
a. Number of faces:
b. Number of edges:
c. Number of vertices:
2. The two parallel faces of a triangular prism are called its .
3. The sides connecting the bases are always in shape.
4. Calculate the volume of the triangular prism shown below.
5. A triangular prism has a base with a base length of 12 cm and a height of 5 cm. If the height of the prism is 10 cm, what is its volume?
6. Find the surface area of a triangular prism whose bases are right triangles with legs of 3 cm and 4 cm, and a hypotenuse of 5 cm. The height of the prism is 6 cm.
7. Which of the following is NOT a face of a triangular prism?
Rectangle
Square
Triangle
All of the above can be faces
8. The height of a triangular prism is always the same as the height of its triangular base.
True
False
