Question

How many tiles of dimension 22.5 cm x 10 cm x 7.5 cm can be painted if the paint is sufficient for the surface area 2812.50 m2 (meter sq.)

Answer 1

30 000 tiles

Explanation:

Firstly convert the dimensions into metres

Then find the total surface area for one tile...in its....;

T.Surface area = 2(0.225 × 0.1) + 2(0.1 × 0.075) + 2(0.225 × 0.075)

Total surface area of one tile = 0.09375m^2

Then divide it into the surface area that the paint can be applied to....

2812.50 ÷ 0.09375 = 30 000 tiles
