Our bridge in real life (1:1) will be
-
length = 270-280 meters
-
height = 70-100 meters
convert to centimeters
-
length = 27000-28000 cm
-
height = 7000-10000 cm
Our drawings will be 1/1000 the size of the bridge in real life. Divide the length and height by 1000
-
length = 27-28 cm
-
height = 7-10cm
