The bus stop

The bus stop waiting room has the shape of a regular quadrilateral pyramid 4 m high with a 5 m base edge. Calculate how much m2 roofing is required to cover the sheathing of three walls, taking 40% of the additional coverage.

Correct answer:

S =  49.5284 m2

Step-by-step explanation:

h=4 m a=5 m q=100%+40%=1+10040=1.4  w2 = h2+(a/2)2 w=h2+(a/2)2=42+(5/2)24.717 m S1=2a w=25 4.71711.7925 m2  S=3 q S1=3 1.4 11.7925=49.5284 m2
