finid how many cm the restaurant is in scale

1foot:2.4cm

obviously multiply both sides by 20
20foot:2.4cm times 20
20ft:48cm

it is 48cm tall

how many bottle caps needed to get to 48
48=height of 1 bottle cap times numer of bottle caps

height of 1 cap=1.2cm
48cm=1.2cm times number of bottle capse
divide both sides by 1.2cm
40=number of bottl capse

needs to be 40 caps tall
