Answer Posted / thiru
Guys actually the cost should be given as Rs.5 per sq.mts
then the answer will be Rs.2200
The walls are 10mts long and 10mts high.So out of 4 walls 2
are of 10*10=100sq.mts area (length * height)
2*100=200sq.mts
Two walls are of 8*10 = 80(width*height)
2*80=160
Roof is 8*10=80sq.mts (length*width)
Total surface area : 200+160+80 = 440sq.mts
Total cost: 440*5= Rs.2200
