Question

Find the outside surface area. Note that the container may not have a top. Assume a = 2 in., b = 1 in., c = 1.4 in., d = 2 in., e = 1.5 in.

Answer 1

excuse me, what do a, b, c, d, and e stand for?

Answer 2

ya, what are a, b, c, d, and e

Answer 3

and you did not mention the very thing is a sphere or cube or something else

Answer 4

sorry im tryiing to get it right now

Answer 5

The three rectangles: Area = ab + bc + bd
The two triangles: Area = (1/2)ae + (1/2)ae = ae

Answer 6

good, so you can see that the object is a triangular prism, specifically here with two identical triangles parallel to each other vertically. notice that the sides of the tri-prism are all rectangulars. set the outside surface area as S. then S=S1+S2+S3+S4(S1 stands for the area of the bottom triangle, S2, S3, S4 the areas of the front, left and the right sides.)=1/2*ae+ab+db+cb=...(do you still need the answer?)

Answer 7

sklee, you probably ignore the important information that the container may not have a top!

Answer 8

Ya, I just give it as included. So it depends on the full questions. If the container is open, then can just reduce (1/2)ae

Answer 9

yes if you dont mind

Answer 10

good!!!

Answer 11

let's work out the answer as fast as possible

Answer 12

ok.

Answer 13

so i add up all the sides which comes out to 7.9 right?

Answer 14

6.9, probably.

Answer 15

7.9,!! I'm sorry.

Answer 16

ok, ya i got 7.9

Answer 17

wait, wait, 0.5*2*1.5+(2+1.4+2)*1=6.9

Answer 18

kinna dizzy...

Answer 19

is 6.9 the answer? so we have to multiply by 0.5?

Answer 20

yep.
