To find the surface area of the box, we need to find the area of each face and then add them all together.
The box has 6 faces:
- 2 rectangular faces: 3 in x 1 in
- 2 square faces: 1 in x 1 in
- 2 square faces: 3 in x 3 in
First, find the area of each face:
- Area of rectangular face = 3 in x 1 in = 3 in^2
- Area of square face = 1 in x 1 in = 1 in^2
- Area of square face = 3 in x 3 in = 9 in^2
Next, add up the areas of all the faces:
3 in^2 + 3 in^2 + 1 in^2 + 1 in^2 + 9 in^2 + 9 in^2 = 26 in^2
Therefore, the surface area of the box is 26 in^2.
