📐 Part 1: Identifying Nets

1. Which of these nets would fold into a rectangular prism?

A net with 6 rectangles arranged in a cross shape

A net with 4 triangles and 1 square

A net with 3 rectangles only

A net with 8 rectangles

2. How many faces does a triangular prism have?

3

4

5

6

3. A square pyramid net must include:

One square base

Four triangular faces

Six rectangular faces

Two triangular faces

✏️ Part 2: Drawing Nets

4. Draw a net for a rectangular prism with dimensions 4cm × 3cm × 2cm. Use the space below and label each face.

5. Draw a net for a triangular prism where the triangular base is an equilateral triangle with 3cm sides and the prism is 5cm long.

6. Sketch a net for a square pyramid with a base of 4cm × 4cm and triangular faces with a height of 6cm.

🧩 Part 3: Problem Solving & Reflection

7. Look at each description below. Decide if the net will fold into a proper 3D solid. Circle YES or NO and explain your reasoning.

a) A net with 2 triangles and 3 rectangles all connected in a line.

Will fold correctly: YES / NO

b) A net with 1 square and 4 triangles, where the square is in the centre and triangles are attached to each side.

Will fold correctly: YES / NO

8. A rectangular prism has a volume of 60cm³. If the base is 4cm × 3cm, what is the height? Show your working.

9. Reflection: In 2-3 sentences, explain the relationship between a net and its 3D solid. Include the terms "faces," "edges," and "fold" in your answer.

10. Challenge: If you were to design a gift box in the shape of a triangular prism, what measurements would you need to know to draw an accurate net? List at least 3 measurements.
