(i) The number of tiles to be used for the whole floors and
(ii) The cost of tiles to be used if a crate of 80 tiles cost 1250.00naira.
ANSWER
Area to be tiled: (25m x 16m) x 2= 800m²
Area of one tile: (0.2 x 0.15)m
2 = 0.03m²
No of tiles to be used = 800m²/0.03m²
= 26666.6 tiles= 26667 tiles
Allowance of 5% = 5/100 x 26667=1333tiles.
Total no of tiles needed = 26667+1333 = 28000 tiles.
(ii) The cost of 1 crate of tile =1250.000naira
1 crate contains 80tiles, therefore 28000 tiles will be contained in (2800θ/80) = 350 crates
→ 350 crates will cost 1250 x 350 = 437,500naira (N437,500:00)
