The answer is 1.5 I think
V= x*(10-2x)(8-2x)
for greatest volume, differentiate v w.r.t x and equate to 0,
dv/dx= (10-2x)(8-2x) + x(-2)(8-2x)+ x(10-2x)(-2)=0
you get x from solving the quadratic equation. volume will be max at that x
Answer:
x ∈ ℝ
Step-by-step explanation:
Since this is a constant function, this domain is the set of all real numbers.
Hope this helped! :)
