Answer:

48m² ; 8 : 1 ; 1440 m³

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
