$sin^{2}x \ cos^{2} x= \frac{1}{2} (1-cos2x) \times \frac{1}{2} (1+cos2x) \\ = \frac{1}{4} (1- cos^{2} 2x) \\ = \frac{1}{4} ( sin^{2} 2x +cos^{2} 2x- cos^{2} 2x) \\ = \frac{1}{4} ( sin^{2} 2x) \\ = \frac{1}{4} ( \frac{1}{2} (1-cos2(2x))) \\ = \frac{1}{8} (1-cos4x) \\ \frac{d}{dx} (sin^{2}x \ cos^{2} x)= \frac{1}{8} \frac{d}{dx} (1-cos4x) \\ = \frac{1}{8} [-4(-sin4x) \\ \frac{1}{2} sin4x$

Answer:

You can hold 188.19 or a rounded 188 pounds per cubic feet

Step-by-step explanation:

First we need to find the area which is 271

I found this using the formula 2(WL+HL+HW)

If you can fit 271 square feet then you need to divide that by 4 to find cubic feet.

if you do this you get 67.75 cubic feet

next divide 67.75 by 0.36

you get 188.19
