A square pyramid has one square base and four triangular sides. How many total faces does this shape have?
Answer: 5
A square pyramid has 5 faces: 1 square base plus 4 triangular lateral faces.
The net of a triangular prism contains exactly how many faces?
Answer: 5
A triangular prism has 5 faces: 2 triangular end caps and 3 rectangular side panels.
A net consists of a central equilateral triangle with one equilateral triangle attached to each of its three edges. When folded, this creates:
Answer: A tetrahedron
One central triangle plus three attached triangles gives 4 total faces, which fold into a tetrahedron (triangular pyramid).
A hexagonal prism net contains two hexagonal end faces and how many rectangular side faces?
Answer: 6
A hexagonal prism has 6 rectangular side faces — one for each edge of the hexagonal base — plus 2 hexagonal end faces.
A regular octahedron has 8 equilateral triangular faces. Its net therefore contains:
Answer: 8 triangles
The net of any polyhedron contains all of its faces laid flat, so an octahedron's net has all 8 triangular faces.
A pentagonal pyramid has a pentagon as its base and five triangular lateral faces. How many edges does this shape have in total?
Answer: 10
A pentagonal pyramid has 10 edges: 5 edges around the pentagon base plus 5 lateral edges rising from each base corner to the apex.
The net of a cylinder consists of two circles and one rectangle. The dimension of the rectangle that wraps around the cylinder must equal:
Answer: The circumference of the circular ends
The rectangle wraps around the curved surface of the cylinder, so its wrapping dimension must equal the circumference (2πr) of the circular ends.
