Visualising solid shapes is a very useful skill. We can see the hidden parts of a solid shape. For example, when a cuboid with a square face is cut vertically, then each face is a square. The face is a cross section of the cuboid.

Three-dimensional objects or solids have length, breadth and height, and look different from different points of view.

Sections of solid shapes can be viewed using three ways:

â€¢ Viewing the cross sections

â€¢ Using shadows

â€¢ Viewing at certain angles

A solid can be viewed from different angles. Viewing a solid from the front, side and top are the three most common ways of viewing it.

Cutting or slicing a solid will result in its cross-section, which is also one way of viewing it.

Observing the two-dimensional shadow of a three-dimensional solid is another method of viewing a solid.

Shadows of solids are of different sizes depending on the position of the solid and the position of the source of light.
