A company wishes to manufacture a box with a volume of 36 cubic feet that is open on top and is twice as long as it is wide. Fin

Nimfa-mama [501]

Answer:

Width is 3 ft

length is 6 ft

Step-by-step explanation:

Let x = the width

Let 2x = the length

Let h = the height

We know that volume is given v = l×b×h

so we have v = volume $= x*2x*h$

$2x^2*h = 36$

$h = \frac{18}{x^2}$

surface area include 2 ends + 1 bottom and 2 sides excluding top

$S.A. = 2(x*h) + 1(2x*x) + 2(2x*h)$

$S.A. = 2xh + 2x^2 + 4xh$

we have calculate $h = = \frac{18}{x^2}$

$S.A = 2x^2 + 6x \frac{18}{x^2}$

$S.A = 2x^2 + \frac{108}{x}$

By graphing above equation we can calculate the value of x

Minimum S.A when x is 3 is the width so

2(3) = 6 is the length

$h = \frac{18}{3^2} = 2$
