Here are three nets of solids labelled A, B and C. Which net could make a cube? Explain your answer.
Figure (to be drawn): Three nets, each made of six equal squares, are shown on a grid. Net A: six squares in a single straight row (a 1 by 6 strip). Net B: a row of four squares side by side; one extra square is attached above the second square in that row, and one extra square is attached below the third square (a cross-like shape). Net C: six squares arranged as a solid rectangle, two rows of three squares each.
