I really need help. Please help I have a final tomorrow.

52 units

Step-by-step explanation:

[] First, we will assume that each square in the grid is equal to one unit.

-> You can count each square in the shape which leads to 52, but I have provided the mathematical way below

[] Since this is a rectangular prism we know we will need to find the area of 6 rectangles for the total surface area.

[] Using the numbers they gave us, and thinking of the layout of a rectangular prism, we can find the side lengths of each rectangle.

-> See attached for my work on this step, it is shown in red

[] We can then do the multiplication for the area of each rectangle, and add them together.

-> For a quadrilateral, L * W = A

        - L is length

        - W is width

        - A is area

-> See attached for my work on this step, it is shown in blue

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)
