The question, in short
From a cuboid net with four congruent rectangles and two congruent squares, rectangle height 5 cm and square side 2 cm, find the total length of all the cuboid's edges.
Summarised in our own words. Use the official paper for the exact wording and the diagram.

- 1The cuboid is 2 cm by 2 cm by 5 cm
- 24 edges of 5 cm: 4 × 5 = 20
- 38 edges of 2 cm: 8 × 2 = 16
- 420 + 16 = 36 cm
