Question

What is the total cost of painting of a class room including ceiling, if the size of length is 6m, breadth is 5m and height is 4m. (Painting + labour cost Rs.150/- per sq.m)

Answer 1

Step-by-step explanation:

the the length of classroom is equal to 6m.

breadth of the classroom is equal to 5 metre

height of classroom is equal to 4 metre

so in this problem we have not painted the base so we have to find the area of four walls and ceiling,

Formula:- curved surface area of valves + area of ceiling

2(l+b)h +lb

2(6+5)4+6×5

=118 m²
