The formula is:
Total time = (hose1 * hose2) / (hose1 + hose2)
Total time = (5 * 4) / 5 + 4
Total time = 20 / 9
Total time = 2 + (2/9)
Total time = 2.22222...
I am assuming this is a trapezoid.
The area of a trapezoid is : A=(B1+B2)H/2
Plug in the numbers to get:
18=(6+B2)*2/2
18=6+B2
18-6=6-6+B2
B2=12
It is impossible because it's base is not circular. A solid of revolution is <span>obtained by rotating a </span>plane curve<span> around some </span>straight line, that is, <span>the </span>axis of revolution that lies on the same plane. The closest to a square pyramid applying this concept is by rotating a right triangle around the opposite or adjacent side (the axis), but the shape that you get is a straight circular cone.
