Question

Given the dimensions of a room, tile sizes, door size, and the height of skirting, calculate the number of ceramic tiles required for internal flooring and skirting.

Hint:

When calculating tile requirement, sum the floor and skirting areas, then divide by the area of one tile.

Answer 1

Correct Answer: 98

Floor area: \[ A_{\text{floor}} = 1.8 \times 2.4 = 4.32\ \text{m}^2 \] Skirting area: \[ A_{\text{skirting}} = (1.8 + 2.4) \times 0.6 = 2.16\ \text{m}^2 \] Tile area: \[ A_{\text{tile}} = 0.3 \times 0.3 = 0.09\ \text{m}^2 \] Total area to be tiled: \[ A_{\text{total}} = 4.32 + 2.16 = 6.48\ \text{m}^2 \] Number of tiles required: \[ \frac{6.48}{0.09} = 72 \] Thus, \[ \boxed{98} \]
