Glass

How many glass are needed to produce glass with base regular 5-gon if one base triangle in the base is 4.2 square cm and the height is 10 cm?

Correct result:

S =  195.6848 cm2

Solution:

S1=5 4.2=21 h=10 S1=5/4 a2 tan(54) a=4 S1/5/tan54=tan3π/10=3.4937 o=5 a=5 3.493717.4685 S=S1+o h=21+17.4685 10=195.6848 cm2
