Find the area of each side and add together... that's surface area I'm having a brain fart haha What is it you want to find?

perimeter of the base times height of the prism + 2Base = Total Area

Well the 2B part is easy. 2(area of the triangles)

Area of Triangle : 1/2 times 9 "correct" ?
 one year ago

johnsonshelby Group TitleBest ResponseYou've already chosen the best response.1
1/2 time base of the triangle times the height of the triangle. Because you are only given the base, you need to find the height.
 one year ago

Dallasb22 Group TitleBest ResponseYou've already chosen the best response.0
And to find the height we use pythag theorem correct?

So your new base would be 1.5 and the hypo would still be 3, yep
 one year ago

Dallasb22 Group TitleBest ResponseYou've already chosen the best response.0
So the height would be a^2?
 one year ago

johnsonshelby Group TitleBest ResponseYou've already chosen the best response.1
c= 3, b=1.5, and yep a= a
 one year ago

johnsonshelby Group TitleBest ResponseYou've already chosen the best response.1
so when you plug into pythag, you would get that

So i find the area of the triangle and multiply it by 2 Then i add ?
 one year ago

johnsonshelby Group TitleBest ResponseYou've already chosen the best response.1
add that to the (perimeter of the base x height), which would be (3+3+3)(6)

Area of Triangle = 1.5√6.75 correct?
 one year ago

phi Group TitleBest ResponseYou've already chosen the best response.0
btw, people would write \[\sqrt{6.75} \] as \[ \frac{3 \sqrt{3}}{2}\]

Okay i got it. Thanks so much!! I just needed a refresh it's been awhile :)
 one year ago

Dallasb22 Group TitleBest ResponseYou've already chosen the best response.0
So it would be 4.5√3 / 2 @phi ?
 one year ago

phi Group TitleBest ResponseYou've already chosen the best response.0
generally you don't mix decimals and fractions i.e. 4.5/2 If you have a multiple choice you probably would see the answer as a pure fraction \[ \frac{4}{9}\sqrt{3} \]
 one year ago

phi Group TitleBest ResponseYou've already chosen the best response.0
double that for the other triangle now you have 3 faces that all look the same size 3x6 3 faces each 18 = 54 plus the two triangles 8/9 sqrt(3)

Other triangle?

phi Group TitleBest ResponseYou've already chosen the best response.0
you have two triangles (the ends) and 3 "side faces" right?

Yeah my bad, sorry
