Tim takes his 3 children trick or treating.  They are out for 4 hours.  Each hour they visited 5 houses.  Each house gives 3 treats per kid.  How many treats do his children get in total?
They visit 4*5=<<4*5=20>>20 houses
That means each child get 20*3=<<20*3=60>>60 treats
So in total they get 60*3=<<60*3=180>>180 treats
#### 180
