Calculate the surface of a regular eleven-sided prism; if the area of its base is 58 cm2, the edge of the base is 6cm long, and the height of the prism is 21 cm.

Correct answer:

S =  1502 cm2

Step-by-step explanation:

S1=58 cm2 a=6 cm h=21 cm n=11  o=n a=11 6=66 cm  S2=o h=66 21=1386 cm2  S=2 S1+S2=2 58+1386=1502 cm2
