Set up and Label the proportion

Answer and round your answer to the nearest whole number.

A 6 ft tall tent standing next to a cardboard box casts a 9 ft shadow. If the cardboard box casts a shadow that is 6 ft long then how tall is it?

6/9 = x/6 or 6:9::x:6

Either way, solve for x.

6 feet tall

To set up and label the proportion, we can use the following information:

Let "x" represent the height of the cardboard box.

Height of the tent = 6 ft
Length of the tent's shadow = 9 ft

Height of the cardboard box = x ft
Length of the cardboard box's shadow = 6 ft

Now we can set up the proportion using these values:

(Height of the tent) / (Length of the tent's shadow) = (Height of the cardboard box) / (Length of the cardboard box's shadow)

6 ft / 9 ft = x ft / 6 ft

To find the value of "x," we can cross-multiply and solve for it:

6 ft * 6 ft = 9 ft * x ft

36 ft^2 = 9 ft * x ft

Now, we can divide both sides of the equation by 9 ft to isolate "x":

36 ft^2 / 9 ft = x ft

4 ft^2 = x ft

Since we are asked to round the answer to the nearest whole number, we would round x to the nearest whole number. In this case, x = 4 ft.

Therefore, the height of the cardboard box is approximately 4 ft.
