What is the dimension of the standard concrete monuments defining the positions of barangay boundaries?

• A. 25 x 25 x 100 cm
• B. 20 x 20 x 100 cm
• C. 30 x 30 x 100 cm
• D. 40 x 40 x 100 cm

Answer: (B)

This question focuses on the standard size of concrete monuments used to mark barangay boundaries. A square cross-section of 20 cm by 20 cm with a length of 100 cm is used because it strikes a balance between durability and practicality. The 20 cm square gives enough mass and robustness to resist disturbance and weathering, while remaining straightforward to manufacture and set in the ground. The 100 cm length provides enough buried depth to anchor the monument securely and enough portion above ground to be easily located and referenced during surveys. Larger sizes would be unnecessarily bulky and costly, while smaller ones might not hold up under field conditions. Therefore, the 20 x 20 x 100 cm dimension is the standard.
