Answer:
₹15.84
Step-by-step explanation:
given outer surface area of a wooden box is painted.

breadth = 60cm
height = 40cm
Total surface area of the box/cuboid
= 2{lb + bh + lh}cm sq
= 2 {75 x 60 + 60 x 40 + 75 x 40} cm sq
= 2 { 9900 } cm sq
= 19800 cm sq
= 1.98 m sq
Cost of painting the box
= ₹ (1.98 x 8)
