Paper box

Calculate the consumption of paper on the box-shaped quadrangular prism with rhombic footstall, base edge a=6 cm and the adjacent base edges forms an angle alpha = 60 °. Box height is 10 cm. How many m2 of the paper consumed 100 such boxes?

Correct result:

S =  2.71 m2

Solution:

S=100(4610+62sin60)/10000=2.71 m2
