So, I can't give you the answer with the appropriate formulas or w/e but this is how I figure it out in my head
Find the ratio between the yard stick and it's shadow
36/21 = 1.71
This means that object creating the shadow is 171% taller that its shadow is long
Find the amount of inches in 168 feet (this is to be more accurate with your answer)
168 * 12 = 2016 inches
Multiply the previous number by the ratio found before
2016 * 1.71 = 3447.4 inches (or 287.3 feet)
If a 36 inch yardstick casts a 21 inch shadow, a building whose shadow is 168 feet is 287.3 feet tall

Another answer:
Using trigonometry will give you a more accurate answer
Tangent ratio = opposite (the yardstick) divided by the adjacent (yardstick's shadow)
Tangent ratio = 36/21 = 12/7 in its lowest terms
Now rearrange the formula to find the height of the building
Tangent ratio*adjacent (the building's shadow) = opposite (the building)
12/7*168 = 288
The height of the building is 288 feet.

D/G = x/C The x is the height of the neighboring building. Just cross-multiply, then divide.
h = height of tree 150 / 20 = h / 2 h = (150/20) X 2 h = ? (you figure it out)
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.
1.8 meters. The ratio of object to shadow is 10:6. Therefore if the object is 3, the shadow is 1.8 ( 6/10x3).
If the lamppost is not the light source then lampost's shadow is 112/(64/20) ie 35 inches.
That depends on the height of the yardstick whose height has not been given.
It depends exactly how long the shadow of the pole is... multiply whatever it is by 36/15 to get the answer.
208 ft pole
To cast a 19 foot shadow the building would have to be 26.91 feet tall. Each foot of building/tree casts 8.47 inches of shadow.
If the building casts a shadow, then the sun is out, and any man who is not standing in theshadow of the building will cast a shadow of his own, no matter how short or tall he may be.(If you had told us the length of the man's shadow, it would have been a completely differentquestion, and we could have had a completely different answer to offer in response.)
That varies depending on the height of the sun, whether the shadow is cast on a sloping surface and so forth.

Everything has a shadow if the sun is shining or a lamp is on in a building. If you see a shadow without a light source my guess would be that it's evil.
24 feet 6 inches to be exact 12*3=36 168/12=14 14*6=84+84=168 21*14=294 12/294=24 R6
The biggest shadow I have personally seen is probably the one from the Empire State Building.
D/G = x/C The x is the height of the neighboring building. Just cross-multiply, then divide.
Hold a yardstick perpendicular to the ground, and measure the shadow. Make a proportion, then measure the tree's shadow. Use the proportion to compute.
