Question

Shown below are three perspective views of the same solid object. Count the total number of surfaces in the object. Assume that the hidden surfaces are flat.

Hint:

In a 3D object, count both the visible and hidden surfaces, as all contribute to the total surface area.

Answer 1

Step 1: Understand the solid.
The given object is a 3D solid with several faces visible in the three perspectives. The visible faces can be counted directly from the given views, and we will include the hidden surfaces as well, assuming they are flat.
Step 2: Count the surfaces.
Based on the shape of the object, it appears to have 6 visible and 6 hidden surfaces. Thus, the total number of surfaces is 12.
\[ \boxed{12} \]
