Correct Answer - Option 4 : L = 2B + t
Explanation:
Brick length (L), width (B), and thickness of mortar (t) in the brick masonry are related to each by the relation:
L = 2B + t
Here mathematically,
Length of brick = 19 cm
Width of brick = 9 cm
Thickness of mortar = 1 to 1.2 cm
Modular Bricks:
Standard size of brick = 19 cm × 9 cm × 9 cm
Nominal size of a brick with mortar = 20 cm × 10 cm × 10 cm
Non Modular Bricks:
Conventional size of brick = 22.4 cm × 11.4 cm × 7.6 cm
