Question

Modular bricks of nominal size 20 x10x10 cm and 20% of the volume is lost in mortar between joints. Then what is the number of modular bricks required per cubic meter of brickwork

Answer 1

∴The number of modular brick required per cubic meter of brickwork is 63

Step-by-step explanation:

Given modular bricks of size 20cm×10cm×10cm

The volume of brick is = 20×10×10 $cm^{3}$=2000$cm^{3}$

Since 20% of volume is lost .

Now the volume of brick =2000×80%$cm^{3}$=1600$cm^{3}$

1$m^{3}$= $100^{3}$$cm^{3}$

The number of brick =$\frac{1000000}{1600}$=62.5≈63

∴The number of modular brick required per cubic meter of brickwork is 63
