Answer: 
Step-by-step explanation:
You can use the following formula to calculate the surface area of the right rectangular prism:

Where "w" is the width, "l" is the length, and "h" is the height.
Knowing that this rigth rectangular prism has a length of 8 centimeters, a width of 3 centimeters and a height of 5 centimeters, you can substitute these values into the formula.
Then, the surface of the right rectangular prism is:
![SA = 2[(3cm*8cm) + (8cm*5cm) + (5cm*3cm)]\\\\SA=158cm^2](https://tex.z-dn.net/?f=SA%20%3D%202%5B%283cm%2A8cm%29%20%2B%20%288cm%2A5cm%29%20%2B%20%285cm%2A3cm%29%5D%5C%5C%5C%5CSA%3D158cm%5E2)
Answer:
x=5, y=3
Step-by-step explanation:
1) x+3y=14,4x+5y=35
2) x+3y=14
3) x=-3y+14
4) 4(-3y+14)+5y=35
5) -12y+56+5y=35
6) -7y+56=35
7) -7y=-21
8) y=3
9) x=-3\times 3+14
10) x=-9+14
11) x=5
finale and last : x=5,y=3 ✅
So first write out the expression:

take two 10's from the top to cancel with the two 10's on the bottom.
3.9/1.3 is 3.
The answer is 3*10^3
