There are two things you need to know. You need to know h - the height of the object that will cast the shadow (assume it's all vertical). And then you need to know the angle (theta we'll call it) of the sun with respect to the vertical object of height that will cast the shadow.
The higher the sun the higher the angle. In fact in some instances the angle theta can be 0 degrees at noon (depending on location and time of day and year) or almost 90 degrees when the sun is sitting on the horizon. Where do you get this angle? I believe that the US Navy publishes these angles or they may be on line.
Well once you know the angle and the height h, the length of the shadow x is a simple calculation, x = h tan theta, where tan represents the trigonometric function tangent in a right triangle.

How does the length of a shadow change during the yearwhy does this happen?
The length of the shadow (on a flat, horizontal floor) depends on the height of the Sun. If the Sun is higher in the sky, the shadow will become shorter.
How does a flag poles shadow change over a year?
The shadow of a flag pole changes over a year due to the tilt of the Earth's axis. In the summer, the shadow is shorter at noon as the sun is higher in the sky. In the winter, the shadow is longer at noon as the sun is lower in the sky. Additionally, the length of the shadow will also vary depending on the latitude of the location.
How does the position of the sun in the sky relate to the length of the shadow cast by an object?
The position of the sun relates to the length of the shadow cast by an object because, when the sun is above the object there is no shadow yet, when the sun is say to the east of the object a shadow is cast towards the west, the farther the sun for example east the longer the shadow will be towards the west.
When the Sun is high in the afternoon how will be your shadow?
When the Sun is high in the afternoon, your shadow will be shorter and appear directly beneath you. This is because the angle of the Sun is more overhead, resulting in a shorter shadow length.
When is the shortest shadow cast?
The shortest shadow is at noon because the sun is directly above you
What will be the shadow length at 4 pm?
The answer depends on: the height of the item casting the shadow, the location on earth, the time of year, and the inclination of the surface on which the shadow is cast.
Can groundhogs predict the length of winter?
You have to believe because if its sunny outside he will probably see his shadow. If its cloudy he wont. No. A goundhog is NOT a scientific animal that can predict the seasons. Its just a myth.
If a nail is 50 millimeters in length what is its shadow length in millimeters?
Its shadow will be 50 millimeters in length, if you lay it down on a flat surface.
A 3 foot pole casts a 6 foot shadow A 4 foot pole casts an 8 foot shadow Use a linear equation to predict the length of a shadow cast by a 6 foot pole?
Shadow lengths are proportional to the heights of objects casting the shadows. Therefore, calling the shadow length l, the height h, and the proportionality constant k, l = kh. (The intercept is 0 because an object with no height casts no shadow.) Therefore, in this instance k = l/h = 6/3 or 8/4 = 2. then l(6) = 2 X 6 = 12 feet.
What three things do length and position of a shadow changing depend on?
The length and position of a shadow depend on the angle of the light source, the distance between the object and the surface the shadow falls on, and the height of the object casting the shadow.

Does the length of a sun stick control the distance a shadow moves?
yes the length of the sun stick does control the distance the shadow moves
A tree is twice as high as the length of the shadow it casts The distance from the tip of tree to the tip of the shadow is 8 feet What is the length of the shadow that the tree casts?
Since the tree is twice as high as the length of the shadow, we can set up the following equation: 2x = x + 8, where x is the length of the shadow. Solving the equation gives us x = 8 feet, so the length of the shadow that the tree casts is 8 feet.
What is the length of your shadow at midday?

How can you calculate height of a pyramid by measuring the length of its shadow?
By means of trigonometry if you know the angle of elevation or by comparing it with a nearby object if you know its height and shadow length.
