Important Questions from Exploring Some Geometric Themes
A pyramid has a base with 10 sides. How many faces, edges and vertices does it have?
Show answer
11 faces, 20 edges, 11 vertices
A pyramid has 1 base and 10 triangular side faces, so faces = 11. It has 10 base edges and 10 side edges joining the apex to the vertices of the base, so edges = 20. It has 10 base vertices and 1 apex, so vertices = 11. The correct answer is 11 faces, 20 edges, 11 vertices.
A dodecahedron has exactly 43,380 nets. If 12 similar solids are considered one after another, how many nets are there in total?
Show answer
520,560
Multiply the number of nets by 12: 43,380 × 12 = 520,560. The correct answer is 520,560.
An octahedron has 11 different nets. If 5 students each make all the different nets once, how many net copies are made in all?
Show answer
55
Each student makes 11 nets, so 5 students make 5 × 11 = 55 net copies. The correct answer is 55.
A cube balanced on a corner vertex has an isometric projection shaped like what?
Show answer
