Given three views, finding the area (lateral area or surface area) and volume of geometric body is a common question in college entrance examination.

This is the key to returning to an intuitive view. First of all, we should start from the top view and estimate the general structure from the top view. For example, if the top view is a circle, it is estimated that the geometry will be associated with a cone, a cylinder or a sphere, and if it is a polygon, it will be associated with a pyramid or a prism. Then look at the front view and side view to complement it.

In addition, the front height is equal, the side width is equal, and the front length is equal.
