Step-by-step explanation:

We know that in order to find the area of a rectangle, we must multiply the length by the height. Let me make this clearer.
In the grid, the top has a length of 3 centimeters and a height of 6 centimeters. To find the area, we multiply these side lengths.
Now, we know that the area of the top is 18 centimeters.
Simply find the area of each side, then combine the areas at the end to find the <u>SURFACE</u> area.
