To find surface area of a cube, there's a formula that can be used: 6*s^2. You multiply 6 to a side or edge squared.
We know that an edge is 14.5 cm so we square it or multiply the edge by itself.
14.5*14.5 = 210.25 cm^2.
Now, we just multiply that number by 6.
210.25*6 = 1261.5 cm^2.
Hope this helps!
