The longest stick that will fit in the box will be equal to the length of diagonal of the box.

Length of diagonal is given as:

$d = \sqrt{ {l}^{2} + {w}^{2} + {h}^{2} } \\ = \sqrt{ {20}^{2} + {6}^{2} + {6}^{2} } \\ = \sqrt{ 400 + 36 + 36} \\ = \sqrt{472} \\ = 21.725561 \\ = 22 \: inches$

What is the surface area of a cylinder with a diameter of 8 centimeters and a height of 12 centimeters?

Lostsunrise [7]

The formula for this is $A=2 \pi rh+2 \pi r^{2}$ . If the diameter is 8 the radius is 4, so filling in accordingly we have $A=2 \pi (4)(12)+2 \pi (16)$ and $A=96 \pi +32 \pi$ which is $A=128 \pi$ and when you multiply in 3.14 you get that A = 401.92 or B above.
