Answer:

48 cm

Explanation:

The surface area of an object will be all of it's side area's added up.

Looking at this, we can see that there are 4 sides with side lengths 2 and 5, and 2 with side lengths 2 and 2.

The area of a rectangle is it's length times width.

$2 \cdot 5 = 10$

Since there are 4 of these sides:

$10\cdot4 = 40$ .

$2\cdot 2 = 4$

Since there are two of these sides:

$4 \cdot 2 = 8$ .

40 + 8 =48

Hope this helped!
