@Lowkey.S how do you think you find the surface area?

OpenStudy (lowkey.s):

the surface area is the sum of all the areas of all the shapes that cover the surface of the object.

OpenStudy (lowkey.s):

right?

OpenStudy (maddielb):

Ok, now how do you think you would find the surface area of let's say the top of the prism

OpenStudy (lowkey.s):

ok?

OpenStudy (maddielb):

How would you think to do that?

OpenStudy (lowkey.s):

idk never learn this!

OpenStudy (maddielb):

You've never learned it and were given questions on it?

OpenStudy (lowkey.s):

yes pretest

OpenStudy (maddielb):

Ok so, you see where it says 13m and 6m?

OpenStudy (lowkey.s):

yes

OpenStudy (maddielb):

You would multiply those together, and that would give you the area of the top and bottom of the prism.

OpenStudy (lowkey.s):

78

OpenStudy (maddielb):

Now, to do the sides, it would be: 6x5m for the left and right sides, and 13x5m for the front and back sides,

OpenStudy (maddielb):

And then the total surface area for the prism would be all of those added together.

OpenStudy (lowkey.s):

6x5=30 13x5=75

OpenStudy (lowkey.s):

ok

OpenStudy (maddielb):

What do you get?

OpenStudy (lowkey.s):

346

OpenStudy (lowkey.s):

m2

OpenStudy (maddielb):

Yep, I believe that is the answer for that one.

OpenStudy (lowkey.s):
