In our daily lives, whatever objects we see are mostly three-dimensional. For example, chairs, tables, books, stationery objects like pens and pencils, etc. So, when we study mathematics as a discipline and learn measurement of common objects in mensuration, trigonometry, and geometry, we should also learn measurement related to three-dimensional geometry. Again, three-dimensional geometry is a crucial part of analytical geometry. This chapter is also important from the perspective of the board exam. Therefore, students must prepare the chapter very well for a better performance in exams.
