Explanation:

Dimension of room= lbh

=9*8*6.5 = 468.0

dimension of 1 door =2*1.5 = 3.0

dimension of 3 window =3(1*1.5) =4.5

remove the dimension of 3 Windows and 1 door from the room dimension.

468.0 - 3.0*4.5 = 460.5

multiply the cost of whitewashing into total dimension = 460.0*3.80=1749.9

total cost of whitewashing total room = 1749.9
