Answer 2

Answer:

4 times.

Step-by-step explanation:

This is for TSA (Total Surface Area):
    Let the original edge be: x
    Let the new doubled edge be: 2x

The TSA of a cube = 6x^2
= 6(2x)^2
= 6(4x^2)
so now we can see that we have 6 and x^2 so it will become:
= 4 * 6x^2
= 4 * original TSA

So it's 4 times, I hope this helps!
