Step-by-step explanation:
We want to find the surface area of this prism.
There are 6 faces on a rectangular prism, and the opposite faces will have the same dimensions.
2 4 by 3 faces - 2*12=24
2 3 by 5 faces - 2*15=30
2 4 by 5 faces - 2*20=40
24+30+40=24+70=94 cm^2
To solve this you have to use cross multiplication.
This gives you 3(x-5)=2(x+2)
3x-15=2x+4
x-15=4
x=19
