Home » Architecture and Planning Miscellaneous » Architecture and Planning Miscellaneous-topic » Question

A 15 meter long and 3 meter wide driveway needs to be paved with 300 mm X 300 mm square tiles. If each packet contains 30 numbers of tiles, then the number of packets to be procured to pave the whole area is ________________

1. 11.5 to 13.0
2. 18.0
3. 16.5 to 17.0
4. 16.5

Correct Option: C

Area covered by each tile is 300mm × 300mm = 0.3m × 0.3m = 0.09 m²
As each packet contains 30 numbers of tiles,
So area covered by each packet = 0.09.30 = 2.7 m²
Total area of the roadways = 15m × 3m = 45 m²
Therefore, no. of required packets= 45 / 2.7 = 16.67 = 17 packets
