answered-by-expert Expert Answer
In every day life in fact whatever we see around us is 3D only and to justify all the dimensions and to analyse it 3D geometry is very Important.
 
Suppose we want to find the know the dimensions of a building or tower knowing the slope of one of the walls then we can find it using 3D geometry.
