**Estimating Decorative Block Quantity**

Decorative Blocks are molded blocks made of either cement or clay that are widely used to decorate walls and floors and provide ventilation, natural sunlight and shade. Nowadays, decorative blocks are made available in different sizes, designs and varieties.

**HOW TO ESTIMATE THE QUANTITY OF DECORATIVE BLOCKS FOR YOUR PROJECT:**

- Determine the surface area of the decorative block:
- Determine the area of the wall or floor where the decorative block will be applied.
- Divide the surface area of your decorative block with your floor or wall area.

Decorative blocks come in different designs and sizes. Get the right dimensions from the material supplier in order to accurately compute for the number of blocks you will need.

**SAMPLE PROBLEM 1**

Compute for the quantity of square decorative blocks, with dimensions 100mm x 180mm, needed for a wall that is 1.5 meters high and 1 meters long.

**SOLUTION**

- Determine the surface area of the decorative block:
- Determine the area of the wall or floor where the decorative block will be applied:
- Divide the surface area of your decorative block with your floor or wall area.

** Decorative Block Area ** = Length * Height

= (100mm/1000) * (180mm/1000)

** = 0.18m ^{2} **

** Wall Area ** = Length * Height

= 1.5m * 1m

** = 1.5m ^{2} **

** Total No. of Decorative Blocks ** = Wall and Floor Area / Decorative Block Surface Area

= 1.5m^{2} / 0.18m^{2}

** = 8.33 pcs
~ 9 pcs. of decorative bocks **
