Q. How to calculate the quantity of Interlocking Brick Tiles?

Solution :- Step 1) Calculate the Gross Area of Interlocking Brick Tiles :

Size of Interlocking Brick Tiles = (200 mm x 160 mm)

200 mm = 200/1000 = 0.200m

Gross Area = (0.200 x 0.160) sqm = 0.032 sqm.

Step - 2) Calculation for Area of Interlocking Brick.
Deduction :- = 2 x (Area of rectangular portion + Area of Triangle portion)

=2 x ((20 x 80) + 2(1/2x (20 x 20))

= 2 x ((20 x 80) + (20 x 20))

= 2 x ((1600 + 400))

= 2 x 2000

= 4000.00 sqm

= 4000.00/(1000 x 1000)

= 0.004 sqm

Step 3) :- Calculation of Net area of Interlocking Brick Tiles.

Net Area = (Gross Area - Area of Interlocking Brick Tiles/Remaining Area)

Net Area = (0.032 - 0.004)
= 0.028 sqm

Step :- 4) Calculation of Road Area.

Road Area = (L x B) where, L = 25m & B = 4m
= ( 25 x 4)
= 100 sqm

Step :- 5) Calculation of nos of Interlocking Brick Tiles.

Nos of Interlocking Brick Tiles = (Road Area/Net Area)


Quantity = (100/0.028) nos
= 3571.43 nos
= 3571.00 nos.
