Answer:

Step-by-step explanation:
The total surface area can be calculated using the formula

From the diagram

We plug in these values to get;
![S.A=2[5(5)+5(10)+5(10)]](https://tex.z-dn.net/?f=S.A%3D2%5B5%285%29%2B5%2810%29%2B5%2810%29%5D)
![S.A=2[25+50+50]](https://tex.z-dn.net/?f=S.A%3D2%5B25%2B50%2B50%5D)


9 is 25% of 36. That is the correct answer.
