Three Dimensional Shapes

Shapes that can get measured from three different directions are known as three-dimensional shapes. The other name to these shapes is known as solids. The three measurements of three-dimensional shapes are named as length, breadth and height. These three measurements can also be considered as parts of the three-dimensional shape. These shapes are totally different from two-dimensional shapes because these shapes contain thickness.

The three-dimensional shapes which seem to have depth, width and height are considered as solid shapes. You can find many such solid shapes around you. For example mobile phones, notebooks, pencil boxes, etc.

Surface Area and Volume of 3D Shapes

The two measures which are used distinctly with the aim fo define the three-dimensional shapes are:

• Surface Area

• Volume

Surface Area: Surface area is considered as the total area of the surface of a three-dimensional shape or object. This measurement is denoted as the symbol 'SA'. The surface area of a 3D shape is measured in terms of square units. The surface area has three different classifications which are derived out of it. These three classifications are:-

• Curved surface area: This is the area of curved regions of a 3D shape

• Lateral surface area: This is the area of the curved regions as well as the flat regions of a 3D shape but the base is not included in this measurement.

• Total surface area: This is the area of all the regions of a 3D shape including the base of the shape.

Volume: Volume is considered as the measurement of the total space that is occupied by a three-dimensional object or figure. The volume is denoted with the letter 'V'. Students can measure the volume of a 3D figure only in terms of cubic units and nothing else. Volume doesn't have any classifications, it only shows the maximum quantity an object can hold or the maximum space an object can obtain.
