Question

if a statue that is 12 ft tall casts a shadow that is 15 ft long. find the length of the shadow that is 8 ft cardboard box casts

Answer 1

so ratios.
If you don't know what a ratio is, look it up. 
the ratio for the 1st one is 15(shadow):12(actual height)
the next would be x:8
so 12/8 is 1.5
then you divide 15 by 1.5 to get 10
so the shadow should be 10ft long.

Answer 2

Answer:

10 ft

Step-by-step explanation:

Length of the statue = 12 ft

length of shadow of statue = 15 ft.

It means, a 12 ft statue casts shadow of length = 15 ft

a 1 ft statue casts a shadow of length = 15 / 12 ft

Thus, the 8 ft cardboard casts a shadow of length

                     = $\frac{15}{12}times 8 = 10 ft$

Thus, the length of shadow of 8 ft cardboard is 10 ft.
