a) 125 meters : 1 foot
The scale is the real skyscraper's height to the model's. 
525 meters / 4.2 ft
125 meters to 1 ft
125:1

b) 84 pieces
The model is 4.2 feet or (4.2 x 12) 50.4 inches tall.
Each sheet is .6 thick
To find how many sheets are used, divide the model's height in inches by the individual thickness of each sheet
50.4/.6
84 pieces

Hope this helps :)
apologiabiology
model is
4.2 feet=525 meters
scale is normally
1 unit of smalller=x units of bigger
4.2feet=525meters
divie both sidesby 4.24
1ft=125m
scal is 1ft:125m

model=4.2 feet tall
sheet=0.6 in
convert 4.2 ft ot inches
1 foot=12 inches
4.2 foot=4.2 times 12 inches=50.4
so we have

height=50.4 inches
how many 0.6 inches fit aka
0.6 times what=50.4
divide both sides by 0.6
what=84
84 sheets







A. 1ft:125m
B. 84 sheets
