Question

What is the surface area of a cube with a side of length 16 meters?

Answer 1

The answer is c.
SA = 6a^2
6 * 16^2
6 * 256
1536

Answer 2

The answer is C. 1536 m^2

Because it is a cube, you know all sides are equal and that there are 6 sides, so if you work out the area of one face, you can multiply it by 6. 16 × 16 = 256, which is one side, so therefore 256 × 6 = 1536 which is all 6 sides. I hope this helps!
