Answer key

Nets of 3D shapes · for parents and teachers

1
6
A cube has 6 square faces.
2
6
A cube has 6 faces, so a net uses 6 identical squares joined edge-to-edge.
3
True
A net is a flat (2D) arrangement of shapes that folds to make a 3D shape.
4
2 triangles and 3 rectangles
A triangular prism has 2 triangular ends and 3 rectangular sides.
5
Cube → 6 squares; Square-based pyramid → 1 square and 4 triangles; Cuboid → 6 rectangles; Triangular prism → 2 triangles and 3 rectangles
Cube: 6 squares. Square pyramid: 1 square + 4 triangles. Cuboid: 6 rectangles. Triangular prism: 2 triangles + 3 rectangles.
6
5
A square-based pyramid has 1 square face and 4 triangular faces, total 5.
7
True
A cuboid has 6 rectangular faces arranged in 3 pairs of equal opposite faces.
8
12
A cube has 12 edges: 4 along the top, 4 along the bottom, and 4 vertical.
9
6
A triangular prism has 2 triangular faces, each with 3 corners, giving 6 vertices in total.
10
True
There are 11 different nets that fold into a cube, each made of 6 squares.
