(a) (b) (c) (d)

2. draw the following shapes on the given dot grids.

Solid ShapeS

3D shapes are solid shapes or objects that have three dimensions (which are length, width,
and height), as opposed to two-dimensional objects which have only a length and a width.
Some examples of 3D shapes are cubes, cuboids, cones and cylinders.

NeT

A net is a 2D shape that can be obtained by opening a 3D shape.
Look at the following opening of an empty cubical box.

Nets of a Cube

A cube is a 3D shape whose all faces are squares. It has six faces, eight corners and twelve
edges. Some nets of a cube are shown below.
