A two-dimensional figure is a flat figure that is described by its length of sides only. It can be obtained from a three dimensional solid when sliced or truncated.
Truncation is the process of cutting a solid with respect to a given plain. Therefore, when a three dimensional solid is truncated, the face forms a two dimensional figure. An example is when a cube is truncated horizontally, a square can be obtained at the surface.
Answer: C Reason: the median is going to be the number in the middle of all the numbers. Take two pencils and put one on the last number and the other on the first number. Each time the pencils take a step towards each other. The number at which they meet is the median. Hope this helps
