Please check my answers I got A. for both! @ganeshie8
what was ur answer for the last one?
@satellite73 Ahh.. Glad you decided to join us :) @HELP!!!! A for BOTH questions.
i have no damned idea
if you say what you did maybe i can understand it
@HELP!!!! you know how to do these ?
this is what i get for the last one http://www.wolframalpha.com/input/?i=2*23*72%2B2*23*84.25
which fortunately is actually an answer, namely B
yeah on the last one i messed up lol
basically its the surface area
last one I have 8843.5
i messed the last one up forgot the bottom
man i must really be messing up
lats one i get A like you do!
Otay. For the second question: Two of the walls will have an area of 72⋅23= 1656 ; 1656 ⋅ 2 walls= 3312 the other two will have an area of 23⋅84.25= 1937.75 ; 1937.75⋅ 2 walls = 3875.5 and the floor will have an area of 72⋅ 84.25 = 6066 Add the 3 answers you got! 3312 + 3875.5 + 6066= 13253.5 , thus how I got option "A."
that is what you get for asking for help lol lot of confusion but i think it is A and here is my computation http://www.wolframalpha.com/input/?i=2*23*72%2B2*23*84.25%2B72*84.25
I just gave you the computation! -.-
yeah it is the same as mine i got A too
yay , no more confusion? -.- Also, did any of you figure out the first one?
@HELP!!!!
you said A i have no idea first you need to find that missing dimension from the box
When in doubt call @ganeshie8 ...I don't think he's going to come though, he's usually not on and this time.
at* Yay, he's here ! :DD
ok i screwed up that is what you are looking for the surface area of the prism not the pyramid now i have to start all over
doesnt the formula for the surface area of a prism have a square root in it?
i get \(202\) rounded, i guess you go with \(205\)
for the pyramid, subtracting base area(6x5=30) from surface area gives the lateral area : `lateral area of pyramid = 107 - 30 = 77` multiplying it by 2 gives the lateral area of prism `lateral area of prism = 77*2 = 154` add this to the area of bases
Thank you, that's what I got. :)
