I've heard it said that the vertical should be 4 times the size of the base (of the right angle triangle). Therefore if a 12 foot ladder would reach about an 11 foot vertical, it would be placed just under 3 feet from the wall.
I've also seen it said that the angle should be 75.5 degrees.
Personally I do not agree with an absolute. At heights under 10 feet, your center of gravity (especially if you are a very large person) might cause the ladder to move away from the wall while you are climbing, therefore a more shallow angle may be appropriate.
At heights over 20 feet, I like to ensure good pressure against the wall when I am at the top. This feels more secure on a windy day. A more shallow angle can help, but ONLY if the base of the ladder is braced. For instance I've braced the bottom against a big tree, or a long plank that spans between the two wheels of a car.
At heights over 25 feet especially you've just got to rule out all variables because it only takes one fall in a thousand trips up a ladder to end your fun (income, health, life). Stand back and look at your angles, test how the ladder feels as you go up, adjust as many times as you have to, brace the bottom, tie off the top, never compromise.

How much sand in 1 cubic meter with specific gravity 2.5?
2.5*1000 kilograms = 2500 kg approximately. The answer is approximate because the density of pure water at 1 atmosphere and 4 deg C is 0.999972 grams/cc, not 1. This is the value against which specific gravity is calculated.

3 FEET
When A 12-foot extension ladder is placed against a wall To achieve the proper climbing angle approximately how far should the bottom of the ladder be from the base of the wall?
You may set the correct distance by trying different angles so that you feel confortable when climbing the ladder. Approximately between 80 to 130 cm. But it is the correct angle that can tell you the adequate distance from the wall. Only by climbing a ladder you know it. I advise you to put a piece of rubber under the ladder so that it can't slip.
How can I safely secure an extension ladder with a rope?
To safely secure an extension ladder with a rope, follow these steps: First, extend the ladder to the desired height and lean it against a stable surface. Then, tie a rope around the top rung of the ladder and secure it to a sturdy anchor point, such as a tree or a heavy object. Make sure the rope is tight and the ladder is stable before climbing.

Is work done on climbing stairs?
Yes, work is done when climbing stairs. Work is defined as force applied over a distance, so when you lift your body against gravity while climbing stairs, you are exerting force over a distance. The energy expended to lift your body is considered work.
