Solution
The correct option is C 32
In geometry, an edge is where two faces meet in an object.
Cube has 12 edges as in the figure below. Cuboid has 12 edges as in the figure below.
Square Pyramid has 8 edges as in the figure below. ∴ Number of edges of Cube + Number of edges of Cuboid + Number of edges of Square Pyramid = 12 + 12 + 8 = 32
