Answer 1

DIMENSION OFF TILES:

length= 22.5cm

          = (22.5/100)m

          =0.225m

breadth = 10cm

              = (10/100)m

              =  0.1 m

height = 7.5 cm

           = (7.5/100)m

           = 0.075m

surface area= 2812.50 m²

           tiles requires= surface area / volume of tiles

                                 =   2812.5/(0.225×0.1×0.075)

                                 =    

Answer 2

Answer:

30000

not 3000 or 300

correct answer is 30,000 tiles

Step-by-step explanation:

length of tile = 22.5cm = 0.225 m

breadth of tile = 10cm = 0.10m

height of tile = 7.5cm = 0.075 m

now.. total surface area of 1 tile = 2(lb+bh+hl)

2(0.225*0.10 + 0.10*0.075 + 0.075*0.225)

2( 0.0225 + 0.0075 + 0.016875)

2(0.046875)

0.09375 m²

total paint = 2812.50m²

now of tiles painted = 2812.50/0.09375

$\frac{281250 \times 100000}{9375 \times 100}$

$\frac{281250 \times 1000}{9375}$

$\frac{281250000}{9375}$

30000.. this is. the answer..
