Re: estimate/ compute quantity for fence materials

Pls specify dimension of lot, not just area.

The reply from 2diy4 from my inquiry....might help 😉 I have 250 sqm of lot

The critical dimension to know is the length and width of the lot, to determine the perimeter. If squarish, each side of the lot will be approximately 16 meters.

Perimeter times height equals the number of square meters of wall. So 16 meter length of each side times 4 sides times 3 meter height equals 192 square meters.

Each square meter of hollow block wall needs 12.5 pieces of hollow blocks or you need 2,400 pieces.

But you need to remove the area of the posts required for the wall from the computation.

To compute for the amount of cement and sand to fill and set the blocks, multiply the number of square meters of wall by .525 bags of cement and .0437 cubic meters of sand. This is for 6" CHB.

So your wall will require approximately 101 bags of cement and 8.5 cubic meters of sand.

Sir Alex, may formula ka din pag compute ng materials for palitada?

Re: estimate/ compute quantity for fence materials

Sir Alex, may formula ka din pag compute ng materials for palitada?

total plaster volume =
length of wall (meters) x height of wall (meters) x thickness of plaster (meters)
**where plaster thickness ranges from .012 to .025 meters**

plaster volume (in cubic meters) x 12 = no. of bags of cement you'll need
plaster volume (in cubic meters) x 1 = cu. meters of white sand you'll need

Sir, pano pag.compute kung ilan ang magagamit na kabelya (12mm and 8mm) sa paggawa ng pader?
Length ng pader ay 30meters.
Height ng pader ay 9 feet.

Saka kung ilang days yan kayang trabahuin.
Saka kung ilang tao ang kailangang mag.trabaho.

Salamat sir.
