Hint: 

Area of Prism: 
$$SA_{prism}  = Bh$$ B = area of Base

Area of Right Circular Cylinder: 
$$SA_{cylinder} = 2 π r2 + 2 π r h$$

Area of a Hemisphere: 
$$Area_{Hemisphere} = \frac{\pi r^2}{2}$$

anonymous · Answer

for the prism I got 90cm^2  but I am having a heck of a time with b.)

hero · Answer

Actually, for the prism, you might have to compute the lateral area + area of the base  = surface area of prism

hero · Answer

That 6.5 cm is a lateral height, not the prism height

anonymous · Answer

ohy boy I am so lost

hero · Answer

I can show you what to do

anonymous · Answer

that would be great

anonymous · Answer

for a.) I used the formula 2(b)(s) + b^2 and arrived at 90cm^2, that is a formula that was taken from numerous websites and the book.  Now if only I can figure out b.)
