What is the volume of the prism? What is the surface area of the prism? Here is a prism with a pentagonal base. The height is 8 cm. Area of the base 29 square centimeters.

The volume is 232, and the surface area is 234

Step-by-step explanation:

The volume is the base times height, so 29*8 =  232

Surface area: 29 + 29 + 40 + 16 + 24 + 56 + 40 = 234

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
