Question 983958
Hi there,
First consider each of the six faces.
2 x 30cm x 40cm (top and bottom faces)
= 2400cm^2
2x 30cm x 50cm (Each end)
= 3000cm^2
2x 40cm x 50cm (2 sides)
= 4000cm^2
Total =
2400+3000+4000
9,400cm^2
9,400cm^2 = 0.94m^2
20 boxes =
20 x 0.94 = 18.8m^2
18.8m^2 x 45 rupees
= 846 rupees.
Hope this helps:-)
