When a torch is pointed towards one of the vertical edges of a cube, you get a shadow of cube in the shape of
(a) square
(b) rectangle but not a square
(c) circle
(d) triangle
Solution:
We know that
A cube is a 3D solid object with six square faces and all the sides of a cube are of the same length. It is also known as a regular hexahedron and is one of the five platonic solids. The shape consists of six square faces, eight vertices, and twelve edges.
If a torch is pointed towards one of the vertical edges of a cube, the shadow is a rectangle but not a square.
Therefore, the shadow of the cube is in the shape of a rectangle but not a square.
✦ Try This: If we rotate a right-angled triangle of height 9 cm and base 7 cm about its base, we get:
(a) cone of height 7 cm and base 7 cm
(b) cone of height 9 cm and base 9 cm
(c) cone of height 9 cm and base 7 cm
(d) cone of height 7 cm and base 9 cm
