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.

If a 5 ft post cast a shadow of 1.2 ft find the length of the shadow for a 17 ft post?
The length of the shadow is proportional to the height of the post. Thus, if l is the length of the unknown shadow, l/17 = 1.2/5 or l = 4.1 feet. This should be rounded to 4 if the value 5 is not considered to be known to at least two significant digits.
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.
If a woman is standind and she is 64in tall with a 20in shadow and there is a lamppost that is 112in what is the length of the lampost's shadow?
If the lamppost is not the light source then lampost's shadow is 112/(64/20) ie 35 inches.
How high is a tree that casts a 25ft shadow?
You need more information to solve this problem. The length of a shadow depends on the angle of the sun which depends on the time of day.
A building with height D feet has a shadow with G feet as its length. What is the height of a neighboring building with a shadow of C feet?
D/G = x/C The x is the height of the neighboring building. Just cross-multiply, then divide.
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.
At any given time of the day the ratio of an object the length of its shadow is the same for all objects if a 5ft post casts a shadow of a 1.2ft find the length for a 17ft post?
Let the length of the shadow be x and use the tangent ratio: 5/1.2 = 17/x Make x the subject of the equation: x = (17*1.2)/5 x = 4.08 feet
How tall is a boy that casts a 4 ft shadow?
The height of a boy that casts a 4 foot long shadow depends on the angle of the sun. A tangent can be used to calculate his height if we know the angle of the sun using the equation: Height = shadow length x tangent of the angle of the sun. Using a calculator, it is easy to get the value of the tangent for any angle and then complete the equation.
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.
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.
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

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.
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?
We can not tell because we do not know how straight the tree is or if the ground is perpendicular or level.
What would the length of shadow cast by a pole be if the incident rays of the sun were direct?
I am not sure what you mean by "direct" - light tends to travel in a straight line. The length of the shadow depends on the length of the pole, and of the height of the Sun.
