Question

The dimension of model of multistory building are $1m\times 6cm\times 1.25m$. If the model is drawn to a scale $1:60$, find the actual dimensions of the building in meters.
Find ; the volume of the room of the model, whose actual volume is $648$ cubic meter.

Answer 1

$1m\times 6cm\times 12.5m$

$\Rightarrow l=1\times 60m=60m$

$b=0.6\times 60=36m$

$w=1.25\times 6075m$

Volume of the Model of the building

$=648{\left(\frac{1}{60}\right)}^3=\frac{648000000}{(60{)}^3}c{m}^3$

$=3000c{m}^3$
