I thought it was 6 x 5

In order to find the surface area of a solid object you have to find the combined "area" of each side (surface) the object has. In this case the figure folds into a cube with equal side-lengths all around. A cube has six sides, and we need to find the area of individual sides and then add them all up. So, the equation would be Surface Area of Cube= 6(5x5).

or (5x5) added up six times.

For 1 square we have
$$A=5\times5=5^2$$
For 2 squares we have
$$A_{2}=A+A=2A=2(5^{2})$$
Thus for 6 squares we have
$$A_{6}=6(5^{2})$$
You can also think of this as a net for a cube(what I mean by that is basically your figure is just a cube that has been unpacked, or it's sides have been opened)
But for a cube we know that total surface area is given by
$$A_{cube}=6a^{2}$$
where a is your side
This gives the same result when a=5
