Given
L=5m
B=4m
H=3m

Area of wells = 2h(l+b)

2x3(5+4)
=54m²

Area of ceiling =L xb

=5x4 =20m²

Total area to white wash=54+20=74m²

Area of floor =lxb=5x4=20cm²


Cost of 1m² white wash =₹12

Cost of 74m² white wash =12x74=₹888

Cost of 1m² tiling =₹45

Cost of 20m² tiling =45x20=₹900

Total cost =888+900=₹1788
