following has vertices but in
least number?
O Cone
O Prism
O Cuboid
O Pyramid​

Answer 1

Given :  

O Cone

O Prism

O Cuboid

O Pyramid​

To Find : Which  has vertices but in least number

Solution:

Cone has 1 vertex     only as base is circular

Prism  has 2 times the Vertex in base

if triangular prism then  2 x 3 = 6 vertex

Cuboid  has  8 vertex

Pyramid​ has  number of vertex in base + 1

if triangular base then 3 + 1 = 4 vertex

if square base then 4 + 1 = 5 vertex

Hence cone has least number of vertex as one only
