Answer 2

The cost of white washing the room (include ceiling) at 3.50 RS per m is Rs.567

Step-by-step explanation:

Length of classroom = 12 m

Breadth of classroom = 5 m

Height of classroom = 3 m

Area of 4 walls+ 1 ceiling = $2(l+b)h +lb = 2(12+5)(3)+(12 \times 5)=162 m^2$

Cost of white washing 1 sq.m. = Rs.3.50

Cost of white washing 162 sq.m. =162 \times 3.50=567

Hence the cost of white washing the room (include ceiling) at 3.50 RS per m is Rs.567
