An equilateral 1 inch triangle is a plane figure and it does not have a cross-sectional area in any meaningful sense, just an area. Its area is 0.43 = sqrt(3)/4 square inches.

It is approx 0.003068 square inches.
Usually it means a piece of wood/lumber that has a cross-sectional area of 4 square inches, meaning that the cross section is a square of 2 inch side.
Cross-sectional area = pi*radius2

The cross-sectional area of a 10-inch round metal duct can be calculated using the formula for the area of a circle: A = πr^2, where r is the radius of the duct. For a 10-inch round duct, the radius would be half of the diameter (10 inches), so the radius is 5 inches. Plugging in this value into the formula gives A = π*5^2 = 25π square inches, or approximately 78.5 square inches.

The question can't be answered as asked. PSI (pounds per square inch) is a measure of pressure (or force) over a given surface area, but without knowing the surface area in question, the psi can't be calculated. However, it might help to understand it better by considering that a 1000 pound weight that is spread evenly over a surface area of 1000 square inches will only have a psi of 1. On the other hand, if you take that same 1000 pound weight and put it on a hand truck with two wheels, each wheel having a surface area (the area of wheel in contact with the ground) of 4 square inches, the area beneath each wheel will have a force (or pressure) of 125 psi being placed on it. Hope that helps.
It all depends upon the shape of the container that it is in. For example, if the water weighs 8 lbs per gallon, then the water at the bottom of a container that is a vertical pipe with cross sectional area of 1 square inch will exert a pressure of 8 psi. However, if the water is in a vertical pipe with cross sectional area of 8 square inches, then the pressure at the bottom of the pipe will be only 1 psi.
