What is the surface area of the composite figure? http://oi48.tinypic.com/25jck6u.jpg *Screen Shot* ^

OpenStudy (anonymous):

And how'd you get that?

OpenStudy (anonymous):

Blondie. Help Me.

OpenStudy (anonymous):

*CAUTION* drawing is not drawn to scale... LOLOL

OpenStudy (anonymous):

>.< LOL STOP XD

OpenStudy (anonymous):

no but really are they supposed to be the same?

OpenStudy (anonymous):

What the same?

OpenStudy (anonymous):

like the sides of the pyramid = 4mm and the bottoms of the rectangle thing = 6mm and then the sides 7mm? lol

OpenStudy (anonymous):

Mhm. :)

OpenStudy (anonymous):

NOW HELP MEH. v_v

OpenStudy (anonymous):

well to find the surface area of the whole thing, you first find the surface area of each shape!

OpenStudy (anonymous):

Okay.. and what's the formula to finding it?

OpenStudy (anonymous):

surface area for a rectangular prism is = 2lh+2lw+2wh

OpenStudy (anonymous):

Huh..

OpenStudy (anonymous):

So.. Hold on lemme try lol

OpenStudy (anonymous):

and for the pyramid its = When all side faces are the same: [Base Area] + 1/2 × Perimeter × [Slant Length]

OpenStudy (anonymous):

2*6*7+2*6*6+2*6*6? Or no?

OpenStudy (anonymous):

l=6,w=6h=7 pretty sure lol

OpenStudy (anonymous):

So I messed up a lot.. xD

OpenStudy (anonymous):

Can you plug in the formula and I solve it? xD PLEASE LOL

OpenStudy (anonymous):

lol 2(6*7)+2(6*6)+2(6*7) maybe... lol

OpenStudy (anonymous):

Pssh.. I'll take it. xD

OpenStudy (anonymous):

That's 240..

OpenStudy (anonymous):

lol i bet its easier if you just find the area of each side lol

OpenStudy (anonymous):

Huh. o.o I'm super uper bad at math. SO I have no IDEA what your talkin' bout'.
