Given the dimensions of tiles is 22.5×10×7.5.
So the total surface area is =2{(22.5×10)+(10×7.5)+(7.5×22.5)}
=2(225+75+168.75)
=937.5
Now let the number of tiles required be x.
Therefore,x×937.5=2812.5×2812.5
=>x=(2812.5)²/937.5
=>x=8437.5
So approximately 8438 tiles can be painted.
Hope it helped.
