Answer:

D

Step-by-step explanation:

We need volume of rectangular prism and volume of sphere.

Volume of Rectangular Prism = length * width * height = 10 * 5 * 3 = 150 sq. ft.

3 inches is 3/12 = 0.25 ft

Volume of Sphere = \frac{4}{3} \pi r^3= \frac{4}{3} \pi (0.25)^3=0.065 sq. ft.

<em>How many of these can u fit in 150 sq. ft??</em>

<em />

<em>150/0.065 = 2307.69</em>

<em />

That's not one of the choices, but we can defnitely fit 2294 of the balls. So D is the correct answer.
