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 9
Multiplying that by how many squares there are \(9 * 6 = 54\)
So now we know the total surface area is 54in2
or other wise 6 * 3 * 3 = 54in2
+444
