We will solve as follows:

*We will find the surface area by finding the areas of the smaller rectangles and adding them up, that is:

*Area of top rectangle:


A_1=5\cdot2\Rightarrow A_1=10

*Area of the two smaller rectangles on the side


A_2=2\cdot2\cdot3\Rightarrow A_2=12

*Area of the rectangle in the middle:


A_3=3\cdot5\Rightarrow A_3=15

*Area of the second rectangle [Bottom up]:


A_4=2\cdot5\Rightarrow A_4=10

*Area of the rectangle on the bottom:


A_5=3\cdot5\Rightarrow A_5=15

**Now, the surface area will be:


A_S=A_1+A_2+A_3+A_4+A_5\Rightarrow A_S=10+12+15+10+15
\Rightarrow A_S=62

So, the surface area is 62 squared inches.
