Worked Solution
Step 1: Recall that a cube is a 3D solid bounded by flat faces, all of which are squares.
Step 2: Count the faces of a cube — there is 1 top, 1 bottom, and 4 sides, giving 6 faces.
Step 3: A net is the unfolded outline of every face, so the net must contain one square for each face.
Final: A net of a cube has 6 equal squares.
Answer: 6
Correct answer: 6
