(a) The model of a building is constructed with the scale factor 1: 30.
(1) If the height of the model is 80 cm, find the actual height of the building in metres.
If the actual volume of a tank at the top of the building is 27 m”, find the volume of the tank
on the top of the model.

Answer 1

$\frac{1}{30} = \frac{Height_{model}}{Height_{actual}}$

∴ Actual Height = 80 cm * 30 = 2400 cm = 24m

$\frac{Volume_{model} }{Volume_{Actual} } = (\frac{1}{30})^3 =\frac{1}{27000}$

∴Volume of model  = $\frac{27}{27000} m^3 = \frac1{1000} m^3 = \frac1{10} dm^3 = \frac1{10} l$
