THANK YOU SO MUCH!!

We can cut it into 2 shapes, a cube with a side length of 6, and a rectangular prism with a length of 14, width of 6, and height of 8.

OpenStudy (anonymous):

Surface area of a cube: SA=6a2 SA=6(6)2

OpenStudy (anonymous):

So the SA of the cube is 216. Now let's find the SA of the rectangle: SA=2(wl+hl+hw) Plug in what we know: SA=2((6)(14)+(8)(14)+(8)(6)) Simplify it and you get your answer ^0^

So just do the problem?

OpenStudy (anonymous):
