Answer: 
Step-by-step explanation:
Given
The length of the rectangular prism is
width of the rectangular prism is 
height of the rectangular prism is 
The surface area of the rectangular prism is ![2[wl+lh+hw]](https://tex.z-dn.net/?f=2%5Bwl%2Blh%2Bhw%5D)
Put the values
![\Rightarrow 2[8\times 12+15\times 12+15\times 8]\\\Rightarrow 2[96+180+120]=2\times 396\\\Rightarrow 792\ m^2](https://tex.z-dn.net/?f=%5CRightarrow%202%5B8%5Ctimes%2012%2B15%5Ctimes%2012%2B15%5Ctimes%208%5D%5C%5C%5CRightarrow%202%5B96%2B180%2B120%5D%3D2%5Ctimes%20396%5C%5C%5CRightarrow%20792%5C%20m%5E2)
The surface area of the rectangular prism is 
A + 5x + 2 means . . .
a can be any number
5 is multipled by x
x can be any number
2 stays the same
So it would be . . .
a + 5x + 2
An example of this is a would be 6 and x would be 2 so it would be written as . . .
6 + 5(2) + 2 = 18.
Hope this helps
And have a NICE DAY .... :) :D
