Answer:
48m² ; 8 : 1 ; 1440 m³
Step-by-step explanation:
Scale = 1 : 400
1cm on the model = 400 cm actual
Dimension of store room (model) = 1.5 by 2 cm
Actual dimension :
1.5cm * 400 = 600cm = 600/100 = 6m
2cm * 400 = 800 cm = 800/100 = 8m
Area = Length * width = 6m * 8m = 48m²
2.)
Actual dimension of shop house :
6cm * 400 = 2400cm = 2400/100 = 24m
4cm * 400 = 1600 cm = 1600/100 = 16m
Area of shop house = 24 * 16 = 384 m²
Ratio of shop house to store room
384 : 48 = 8 : 1
C.) if height of shop house = 3.75m
Volume of shop house in m³ :
Area * height
384 m² * 3.75 m = 1440 m³
