$area\ of\ floor\ : A= 8500\ in^2\\\\Tiles:6\ in\ x\ 13\ in\\\\Area\ of\ one\ tile:\\\\A_t=6*13=78\ in^2\\\\Number\ of\ tiles:\ \frac{A}{A_t}=\frac{8500}{78}=108,9\approx109\\\\He\ will\ need\ 109\ tiles.$

Help, I’m stuck. Thank you very much

If you notice, the container is really just two circles, with a diameter of 4 each, and a square with sides of 10.5.

now, if we just get the area of each circle, keeping in mind their radius is half of the diameter, namely r = 2, and get the area of the 10.5x10.5 square, sum them up, that'd be the surface area of the container.

$\bf \stackrel{\textit{2 circle's area}}{2(\pi r^2)}~~+~~\stackrel{\textit{area of the square}}{10.5\cdot 10.5}
\\\\\\
\stackrel{\textit{2 circle's area}}{2(\pi 2^2)}~~+~~\stackrel{\textit{area of the square}}{10.5\cdot 10.5}\implies 8\pi + 110.25$

V=(π)(r^2)(h)

π=3
r=half of the diameter=4
h=12

V=(3)(4^2)(12)
= (3)(16)(12)
= 576 cm cubed
