The volume of metal in a scale model of an mobile phone tower is 54 cm^3. The scale was 1:50. It required 5 ml of paint to give the model one coat.
Find the volume of mental in cubic metres would be required to build the tower.
the scale of volume is the cube of the linear scale, since each dimension is multiplied by the scale.
Then convert that using 1m = 100 cm
The result says that
v = 54 cm^3 * (50/1)^3 * (1m/100cm)^3 = 54*(1/2)^3 = 54/8 = 27/4 m^3
