What is meant by the Net of a Solid?
Nets
A net is a sort of skeleton – outline in 2-D, which, when folded results in a 3-D shape.
OR
A net of a 3-D figure is the shape that can be cut out of a flat piece of paper or cardboard and folded to make the 3D-shape.
OR
A solid figure may be changed into a plane figure by cutting some of the edges of the original figure and opening it out flat as a fold-out. Such a plane figure is called a net of the solid.
Nets for Building Different 3-D Shapes
Net of a Cube
The following figure is a net of a cube which is formed by six squares.
Net of a Cuboid
Given below is the net of a cuboid. This contains two pairs of congruent rectangle.
Net of a Cone
The given below is the net of a cone. This is obtained by cutting a segment of a circle.
Net of a Cylinder
Given below is the net of a cylinder. It is a rectangle with two congruent circle whose circumference is the length of the rectangle.
Net of a Triangular Prism
Given below is the net of a triangular prism. The net consists of three rectangles and two equilateral triangles.
Net of a Triangular Pyramid
This net consists of four triangles in which three are identical isosceles triangles and one is an equilateral triangle.
Net of a Tetrahedron
To construct this, make an equilateral triangle of any measure. Then join the midpoints of these sides to form the inner dotted triangle.
Net of a Square Pyramid
This net consists of a square with an isosceles triangle on each side of the square.
