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)


Answer:
x = 1,3
Step-by-step explanation:



1 2/3 is 5/3 as in improper fraction
The perimeter of a square is the sum of its sides.
Then the perimeter is
P = 4L
Clearing the side we have:
L = (P / 4)
L = (12x + 52) / 4
L = 3x + 13
answer:
The side length of the square is 3x + 13 units
The answer is 3620.0000000000004
