Hi!
To find the surface area, we must first find the area of all of the faces and then add them together.
Because every face is the same size, the formula will be:
6(8 x 8)
6 represents the number of faces and 8 x 8 represents the formula to find the area of each.
6(8 x 8) =
6(64) =
384
The surface area of the cube is 384 square inches.
I hope this helps you!

Answer:
see the explanation
Step-by-step explanation:
Let
L ---> the length of rectangle in cm
W ---> the width of rectangle in cm
The area of rectangle is
![A=LW](https://tex.z-dn.net/?f=A%3DLW)
![A=991\ cm^2](https://tex.z-dn.net/?f=A%3D991%5C%20cm%5E2)
so
---> equation A
we know that
<u><em>Prime numbers</em></u> only have factors of 1 and themselves.
So a rectangle with an area of 991 cm² can only be either
or ![L=1\ cm, W=991\ cm](https://tex.z-dn.net/?f=L%3D1%5C%20cm%2C%20W%3D991%5C%20cm)
