Answer 1

When a torch is pointed towards one of the vertical edges of a cube, you get a shadow of cube in the shape of rectangle but not a square.

Explanation:

• A cube has 6 faces, 12 edges and 8 vertices.

• When light from a torch is pointed towards one of the vertical edges of the cube, the light passes around the shape and casts a shadow.

• The shadow of the cube will take the outline of a rectangle because:

  • The light touches the two adjacent faces that meet at the edge.

  • The height and width of the shadow are determined by the lengths of the cube’s edges.

Therefore, the shadow cast is in the shape of a rectangle.
