fthe room is cuboid
therefore,surface area of cuboid=
2lh+2lw+2hw
2(6×3)+2(6×4)+2(4×3)
36+48+24
=102 sq m
the cost of painting is 4 per m
102×4
=408 rs
hope this helps you

Hi ,
dimensions of the room ,
length = l = 6 m
breadth = b = 4 m
height = h = 3 m
area of the four walls = 2 ( l + b ) h
A = 2 ( 6 + 4 ) × 3
= 6 × 10
= 60 sq m
cost of painting 1 sq m = Rs 100
cost of painting 60 sq m = 60 × 100
= Rs 6000
I hope this helps you.
