Answer:

52 units squared

Explanation:

Since each square in the grid is 1 unit, we can just find the area of all the rectangles and add them up.

First off, let's take a look at the left-most rectangle. It has a length of 4 units and a width of 2 units. The area of that rectangle is 8 units squared. This can also be achieved by counting the number of squares in the rectangle.

Follow this process for all 6 rectangles.

8 + 6 + 6 + 12 + 8 + 12 = 52

Answer:

52 units

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^∇^)
