Question

The paint in a container is sufficient to paint an area equal to \( 18.72 m^{2} \). How many tiles of dimensions \( 24 cm \times 18 cm \times 12 cm \) can be painted with this paint?

Answer 1

Total surface area of each titles = 2(lb + bh + hl)

= 2(24 × 18 + 18 × 12 + 12 × 24) cm²

= 1872 cm²

No. of tiles = \(\frac{18.72\, m^2}{1872\, cm^2}\)

= \(\frac{18.72 \times 10^4\, cm^2}{1872\, cm^2}\)

= 100
