A box of sticks of equal lengths is provided.
The minimum number sticks needed to build a frame to enclose a 3 dimensional volume is
2)We can make cube with the help of 12 sticks.
It will definitely enclose 3 dimensional figure.
1)Also with the help of 6 sticks I can make tetrahedron
Here 3 sticks are require to make base
Also with other 3 sticks,its top is formed
I think it is the answer
3)According to me, it is not possible
4)It is rejected as I make 3 dimensional figure in option (1)
But suggest me the 3 dimensional figure formed by 8 sticks.
Am I doing right ????
