Worked practice questions

Counting all edges of a triangular prism gives how many?

  1. 12
  2. 8
  3. 6
  4. 9
Show answer and solution

Correct answer: D. 9

1. The prism has two triangular ends with 3 edges each, which is 6 edges. 2. Three more edges join the two triangles. 3. So 6 + 3 = 9 edges. _Source: Wikipedia, Triangular prism (CC BY-SA 4.0), Special cases_

A triangular prism has two triangular ends. How many corners in all?

  1. 6
  2. 9
  3. 5
  4. 8
Show answer and solution

Correct answer: A. 6

1. Each triangular end has 3 corners. 2. There are two ends, so 3 + 3 = 6 vertices. 3. Nine is the edge count and 5 is the face count. _Source: Wikipedia, Triangular prism (CC BY-SA 4.0), Special cases_

Which solid has the same cross section all along its length?

  1. Prism
  2. Cone
  3. Sphere
  4. Pyramid
Show answer and solution

Correct answer: A. Prism

1. A prism is a solid with identical ends and flat faces. 2. Slicing it parallel to its ends always gives the same shape. 3. A pyramid and a cone shrink toward the apex, and a sphere changes size. _Source: Math Is Fun, Prisms (mathsisfun.com/geometry/prisms.html), Prisms_
