Question

The number of dimensions, a solid has: (A)(B)(C) (D)

• A. $1$
• B. $2$
• C. $3$
• D. $0$

Answer 1

The correct option is C

$3$

According to Euclid’s postulate the three steps from solids to points as solids-surface-lines-points. In each step, one dimension is lost. The three steps from solids to point are solids-surfaces-lines-points.

A solid has $3$ dimensions, the surface has $2$, the line has $1$and point is dimensionless.
