Answer:

Octagon:

Sum = 1080

One interior angle = 135

14-gon:

Sum = 2160

One interior angle = 154.286

20-gon:

Sum = 3240

One interior angle = 162

Step-by-step explanation:

Sum of angles in a polygon -> sum of angles = (n – 2)180°

one interior angle = sum of angles/n

n = number of sides

one interior angle = sum of angles/n

Octagon:

Sum = 1080

One interior angle = 135

14-gon:

Sum = 2160

One interior angle = 154.286

20-gon:

Sum = 3240

One interior angle = 162

A cube-shaped water tank having 6 ft side lengths is being filled with water. The bottom is solid metal but the sides of the tan
Mekhanik [1.2K]

Answer:

0.033 ft

Step-by-step explanation:

Let g = 32.2 ft/s2 and h be the maximum height that water can be filled before the sides shatter.

Pressure is distributed from 0 to maximum at the bottom like the following equation:

P = \rho gh

So the force generated by water pressure on the side of the tank is

F = PA = \rho ghs/2

where s = 6ft is the side length of the tank. This force cannot be larger than 200lb

\rho ghs/2 \leq 200

62.4*32.2*h*6/2 \leq 200

h \leq 0.033 ft
