Answer:
The volume of the box is
V(x) = 4x^3 -72x^2+320x
Step-by-step explanation:
Here, we are interested in calculating the volume of the box
From what we can see, the shape of the box is a cuboid
Mathematically, the volume of a cuboid is l * b * h
Thus, what we have will be;
x * 20-2x * 16-2x
= x ( 20(16-2x) -2x(16-2x))
= x(320-40x-32x + 4x ^2)
= x(320-72x+4x^2)
= 320x-72x^2 + 4x^3
the volume v(x) will be;
V(x) = 4x^3 -72x^2+320x
Ok, so if janelle earns 16 dollars for 2 hours, then this means that she earns 8 dollars for 1 hour.
So now you will divide 40 by 8 to get 5 hours
