We need to find the area of one square and multiply that by how many squares there are.

3*3(for the area of one)*6(amount of squares)

So 6*3*3 is the correct answer

To find the surface area we have to calculate every square in the problem and we only need to find the area of 1 square and then multily that area by how many squares there are

Formula for a rectangle/square    \(Length * With = area\)

Now we know to make a square all sides must be the same lenght other wise it would be defined as a rectangle

so we can see that all sides are registering as 3 in the problem and inserting this for are lenght and height we get

\(3 * 3 = 9\)

Now we know the area of 1 square is

Multiplying that by how many squares there are   \(9 * 6 = 54\)

So now we know the total surface area is 54in

or other wise 6 * 3 * 3 = 54in2
