Question 929381
The Volume V of a container is modeled by the function V(x)=x^3-3x^2-4x. Let x,x+1,and x-4 represent the width, the length, and the height respectively. The container has a volume of 70 ft^3. Find the container's dimensions.
-----
Solve: x^3-3x^2-4x-70 = 0
----
I graphed the cubic equation and found a zero at x = 5.78..
x = 5.78
x + 1 = 6.78
x-4 = 1.78
