Question 998830
Hi there,
I am assuming the length = 50 cm,
the breadth = 30 cm and the height = 40 cm.
Considering the sides and the top and bottom
and the ends.
Sides: 2 x 50 x 40 = 4000cm^2
Top and bottom: 2 x 40 x 30 = 2400 cm^2
Ends: 2 x 30 x 50 = 3000 cm^2
Total = 9,400 cm^2
9,400 cm^2 = 0.94 m^2
0.94 x rs 15 = rs 14.1
rs 14.1 per tin
rs 281 for 20 such tins.
Hope this helps :-)
