Since hte front and back are the same and they are both triangles. The formula is A=1/2BH
And you can multiply by 2 since the measurements are the same.
A=1/2BH
A=1/2⋅1⋅2
A=1
1⋅2=2

So the front and back's area is 2.
For the sides, the measurements are different so you have to do them separately.

The right side. It is a rectangle so this is the formula.

A=BH
A= 3⋅2.2
A=6.6ft^2

The left side

A=BH
A=2⋅3
A=6

Finally, you add the answers all together and that is the surface area of the prism.

6+6.6+2=14.6

The surface area of this prism is 14.6 sq feet.

We have been asked to investigate two flights, AA flight and U A flight. Both flights are at 33,000 feet, and the flight paths i

Answer:

Both flights approach each other at a speed of 624.70 Knots. The FAA minimum separation is not violated as both airplanes are 7.26 Nautical miles away from each other at the time when one of the flights( flight AA) passes through Frada Heights.

Step-by-step explanation:

To solve this kind of problem, the knowledge of concept of relative velocity is needed as the first question requested how fast the flights were approaching each other. To find the minimum distance between both flights, the closest point of approach between both flights should be taken into consideration which was Frada heights. Flight AA passes through Frada Heights in a shorter time of 0.079 hours. This is the time at which both flights approach each other the closest and so the minimum distance (separation) between them. This was calculated to be 7.26NM which is greater than the FAA's minimum this requirement for flight was not violated.
