vocaloid · Answer

height of pole/length of pole's shadow = height of building/length of building's shadow

let x = height of building
height of pole = 6
length of pole's shadow = 10
length of building's shadow = 220

6/10 = x/220

cross multiply and solve for x

vocaloid · Answer

oh, I guess they're looking for the ratio, so after you find the height of the building, you would divide 

height of building/length of building's shadow

so basically multiply 6*220 and then divide the answer that you get with 10, and that will equal x.
