Let the sides of square base be "x" and height be "h" first come up with expressions for surface area and volume<span>SA=2<span>x2</span>+4hx=600</span>
<span>V=h<span>x2</span></span>Next get h in terms of x and sub it into Volume equation<span>h=<span><span>300−<span>x2</span></span><span>2x</span></span></span>
<span>→V=(<span><span>300−<span>x2</span></span><span>2x</span></span>)<span>x2</span></span>
<span>V=150x−<span>12</span><span>x3</span></span>maximize volume by setting derivative equal to 0<span><span><span>dV</span><span>dx</span></span>=150−<span>32</span><span>x2</span>=0</span>solve for x<span>x=10</span><span> which means h =10 max volume occurs when box is a cube 10^3 = 1000 cm^3</span>
Answer:

The mathematical equation for volume of a cylinder is pi times radius Squared Times height
The radius squared is 36
So 3.14 x 36 =113.04
Then you multiply 113.04 x 7 = 719.28.
Round that number and you get to 791.3.
So the answer is c
