Solid shapes are three-dimensional objects with length, breadth, and height that occupy space and can be felt and touched, whereas 2D shapes have only length and breadth and exist on a plane. The document discusses the definitions and characteristics of 2D and 3D shapes, including their representations as nets and oblique and isometric sketches. It concludes that solid shapes play an integral role in everyday life and have distinct methods of representation.

1. WHAT IS SOLID SHAPE🧐
Solid shapes, also known as solids, consist of 3 dimensions—length,
breadth, and height. They are also known as 3-D (3-Dimensional)
shapes.
These solid shapes occupy some space and are found in our day-to-
day life.
We can feel, touch, and use them.

2. 2D stands for “Two Dimensional”.
A 2D shape has two dimensions-
Length and Breadth.
2D figures are also referred to as plane
figures or plane shapes since these
figures lie on a flat surface.
2D shapes have areas but not volume.
Straight lines make up the sides of the
2D shapes.
2D shapes are drawn using X-axes, and
Y-axes.
Ex:-Circle, Square
etc
3D stands for Three Diamensional
3D shape has 3 diamensions Length,
Breadth and deapth
We see many things around
us which are 3D like ball etc
3D shapes have both ares and volume
3D shapes are drawn using X-axis Y-axis and Z-axis
Ex :- Sphere,Cube etc ,

5. NETS OF SOLID SHAPE
The net of a 3D shape is what it looks like if it is opened out
flat.
A net can be folded up to make a 3D shape.
There may be several possible nets for one 3D
shape.
There are 11 nets in cube

8. OBLIQUE SKETCHES
The oblique sketching is a pictorial representation of an
object, in which the diagram is intended to depict the
prespective of objects in 3 dimensions.
This type of drawing can be done either in a normal, cabinet or
cavalier style.
It allows you to see the depth and orientation of the object,
which can be helpful for showing how it fits or functions in a
system.

10. ISOMETRIC SKETCHES
Isometric Sketch or isometric drawing is a pictorial
representation of an object in which all 3 dimensions are
drawn at full scale.
It looks like an isometric projection. In this case, all the lines
parallel to its major axes are measurable.
An isometric drawing and a net represent the same three-
dimensional object in different ways.

12. CONCLUSION
We use many solid shapes in our day to day life
There are two types of solid shapes , 2D and 3D
The net of a 3D shape is what it looks like if it is opened out flat.
The oblique sketching is a pictorial representation of an object,
in which the diagram is intended to depict the prespective of
objects in 3 dimensions.
Isometric Sketch or isometric drawing is a pictorial
