To calculate the number of Mangalore tiles and battens required to cover an area of 10 sq.m
Size of Mangalore tiles = 41 cm x 24 cm
and it can cover an area of 32 cm x 21 cm
Therefore, Area covered by one tile with overlap = 32 cm x 21 cm = 0.32 sq.m x 0.21 sq.m
= 0.672 sq.m
Therefore, Total number of tiles required = (Area to be covered / Area of one tile with overlap)
= 10 / 0.0672 = 148.81 = 149 Nos.
Length of the ridge tile = 40 cm
The size of teak wood battens is equal to 5 cm x 2.5 cm and are usually fixed at 30 cm c/c
