The solution for s in the given equation is 
The question seems to be incomplete
Here is the complete question:
Solve for s in this equation
Depreciation.
To solve for s, that means we should make s the subject of the equation
From the given equation,
To solve for s, first multiply both sides by n to clear the fraction
We get

Then,

Now, add s to both sides


Then, subtract nD from both sides

∴ 
Hence, the solution for s in the given equation is

Using the formula given for area:
Area = 1/2 (7 +5)4 = 1/2(12)4 = 24 square cm.
Now to find the volume multiply the area by the depth:
24 x 6 = 144 cubic cm.
2x-1.1/4+x/3=2
2x-1/4+x/3=2
2x-1/4+x/3+1/4=2+1/4
2x+x/3=9/4
3(2x+x/3)=3.94
7x=27/4
7x/7=27/4/7
x=27/8
