Answer 1

Step-by-step explanation:

side of box= 30 cm

TSA of box = 6a^2

= 6 X 30 X 30

=5400 cm^2

= 5400/10000

=54/100

cost of painting the box per m^2= 200rs

cost of painting the box from inside as well as from outside = 2 X TSA X 200

= 2 X 54/100 X 200

=2 X 2 X 54

= 4X 54 =216 Rs

Answer = 216 Rs
