Which of these is the net of a cube? Circle the letter: A, B, C, or D.

Essentially, a net of a shape is taking a 3D shape and flattening it. So the way that we will decide which of these is the net of a cube will be to try to visualise folding up the nets and determine whether there are any faces that would overlap.

For example, letter B, if each of these squares represent a side, and we will try to fold this up to be a cube, the two squares that have a dot would overlap. And since they will overlap, they would not make it complete cube. We don’t want any of the sides to overlap.

For option C, if we would imagine that this square would be the base, the bottom, and we will fold everything up and around, we would still be missing a piece of the cube, one of the sides. So option C could not be the net of a cube. For option D, these two squares would end up overlapping.

For option A, we could visualise that this is the bottom. These two squares would be parallel. And these ones would be the ones that connect the two yellow sides, creating a perfect cube. So our answer will be letter A.
