Answer:

Step-by-step explanation:
The figure is a cube
The surface area of a cube is equal to

where
b is the length side of the cube
In this problem we have
substitute

We let the number of years that the two jobs will have the same payment be denoted as t. Equating the wages of these two jobs after t - 1 years will give us an equation of,
22,000 + 4000(t -1) = 26,000 + 2000(t - 1)
The value of t from the generated equation is 3. Therefore, after 3 years the jobs will be paying the same wages.
