Visualising Solid Shapes — Practice

Question 1

A solid has 5 faces and 6 vertices. Find the number of edges using Euler's formula.

Accepted Answer

F - E + V = 2 -> 5 - E + 6 = 2 -> 11 - E = 2 -> E = 9 (a triangular prism).

Question 2

How many faces does a triangular prism have?

Accepted Answer

5 faces: 2 triangular faces and 3 rectangular faces.

Question 3

Which 3D shape has a net consisting of 1 square and 4 triangles?

Accepted Answer

A square pyramid.

Question 4

How many faces, edges, and vertices does a cylinder have?

Accepted Answer

A cylinder has 3 faces (2 circular + 1 curved), 2 curved edges, and 0 vertices.

Question 5

Draw the front view, top view, and side view of a cone.

Accepted Answer

Front view: triangle. Top view: circle. Side view: triangle.
