The side length, s, of a cube is 4x^2+3. if v=s^3, what is the volume of the cube?

a.) 64x^6+144x^4+108x^2+27
b.) 64x^6+48x^4+12x^2+1
c.) 4x^6+36x^4+108x^2+27
d.) 4x^6+12x^4+12x^2+1

The answer to the above problem is 64x6 + 144x4 + 108x2 + 27. I hope it helps.  

Step-by-step explanation:

Labor time = 4 1/2 hours = 4.5 hours
overhead rate = 95% - mostly dependent on labor
retail price of parts = 134.75
total cost of job = 241.98

241.98 - 134.75 = 107.23
107.25 / (4.5 x 1.95) = 107.25 / 8.78 = 12.22 hourly rate

labor : 12.22 x 4.5          =   54.99
overhead: 54.99 x 95%  =   52.24
retail price of parts         = 134.75
total cost of job:                 241.98
