Question 1 of 10
1. Question
What are the three steps from solids to points?
Correct
In each step we lose one dimension. Solid 3 dimension. Surface 2 dimension. Lines 1 dimension. Point has no dimension.
Incorrect

Question 2 of 10
2. Question
What are the number of dimensions, a solid has?
Correct
A solid shape also has a depth. Solids by their nature have an inside and an outside separated by a surface. That’s why solid is a three dimensional structure. It has length, breadth and depth.

Correct
A surface is that which has length and breadth only so it will have two dimension only.
Incorrect
A surface is that which has length and breadth only so it will have two dimension only.

Question 4 of 10
4. Question
A pyramid is a solid figure, the base of which is
Correct
A pyramid is a polyhedron formed by connecting polygonal base and an apex. Each base edge and apex forms a triangle, called the lateral face. It is a conic solid with polygonal base.
