               CHAPTER-10: Visualising Solid shapes
               Worksheet- 1



               1    Which one is a 3D shape?


                        A. Square
                        B. Rectangle
                        C. Circle
                        D. Cube


               2     A three dimensional shape is a solid object which has length _________ & height.

               3    A pyramid with square base has 5 faces and 8 edges. By Euler’s formula, find the vertices
                    of the pyramid.


                        A. 5
                        B. None of these
                        C. 4
                        D. 3


               4    Find the number of faces if the figure has 30 edges and 12 vertices .


               5    Verify Euler’s formula for these solids.













               6    The number of faces of a square pyramid is _______.
