Question

I need help find the surface area of the prism, need someone to explain the formula to me.. :/ (picture below)

Answer 1

how many faces are there in the pic?

Answer 2

5?

Answer 3

I'm really clueless so don't judge me. haha

Answer 4

I don't judge you.
you are correct.
let say A1 is the area of the top one. A1=?

Answer 5

I'm not really sure.. Is it one of the meters on the pic?

Answer 6

let me attach the pic

Answer 7

okay

Answer 8

DAT SIT

Answer 9

Do I add 10 + 10 + 17 + 17 to the the area of the top?

Answer 10

to get the top area*

Answer 11

the area of the rectangle is length * width,
what you say is perimeter

Answer 12

is 17 the width and 10 the length? So.. 17*10? 170

Answer 13

yup

Answer 14

don't forget the unit is m^2

Answer 15

That confused me a little again.. So 17m(squared) = 289

10m^2 = 100 or was I right with 170?

Answer 16

no, 17(m) * 10 (m) = 170 (m^2)
number * number
unit * unit
separately

Answer 17

So I take the area of the top, bottom and sides and those are the units, square them, then add them together? I think I'm making this more confusing than it's supposed to be

Answer 18

when the unit is m, it shows the length of a line
the unit is m^2, it shows the area of a rectangular or a square.
That's why when looking at the units, you can figure out which is which.

Answer 19

I got
A1 =170^2
A2 = 102^2
A3 = 60^2
A4 = 80^2

Answer 20

top : 10 (m)*(17(m) = 170(m^2)
back 10(m)*6(m) = 60(m^2
left (8(m)*6(m))/2 = 24 (m^2) those are triangles, not a rectangular, the formula is
right the same with left= 24(m^2) bottom * height /2
total -----------------------------
278 (m^2)

Answer 21

Well I was off.. Is there anything after adding them together?

Answer 22

m^2

Answer 23

77284?

Answer 24

278(m^2)
i give you all I have, you just read to know why I got that answer
