Question

Count the number of surfaces in the shown solid. 

• A. 21
• B. 23
• C. 25
• D. 27

Hint:

When counting the surfaces of solids, count both the exposed and cut surfaces to ensure accuracy.

Answer 1

The Correct Option is B

Step 1: Identifying the solid.
The given solid appears to be a combination of cubes and cut surfaces. To count the total number of surfaces, we need to account for both the exposed and cut surfaces.
Step 2: Analysis of options.
- (A) 21: This is an underestimation of the number of surfaces.
- (B) 23: This is the correct answer, accounting for all exposed surfaces.
- (C) 25: This is too high, as not all surfaces are exposed.
- (D) 27: This is too many surfaces for the given solid.

Step 3: Conclusion.
Thus, the correct answer is (B) 23.
