Solution
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.
