What is the surface area of this rectangular prism?

160cm^2

Step-by-step explanation:

So the surface area is basicly the sum of all the areas of the rectangles in this prism.

So the formula can be written as  .

The w stands for width, the h stands for height, and the l stands for length.

5cm is the width, 10 cm is the length, and 2 cm is the height.

So inserting all those values for the variabls the formula now looks like this.

.

So 5*10 is 50

2*10 is 20

2*5 is 10

So adding all that up we get 80.

Then multiplyong that by 2 we get 160cm^2.

tube or goog would be a great resource to with that question
