Nets of 3-dimensional shapes

Nets of 3-dimensional shapes

It is possible to represent 3-dimensional shapes into 2-dimensional patterns called nets. If you fold the nets back up, they will be reverted to their original 3-dimensional form. It is way easier to find the surface area and perimeter of a 3D object if we know its net!
