Smaller 3cm = 30mm so 8mm is 22mm smaller than 30mm or 3cm
3cm = 3 x 10 = 30 mm
if you have a box that is 9cm long and 3cm wide then you would say width + length + width + length because the side opposite from 3cm is also 3cm and the side opposite 9cm is also 9cm. so you would add: 9cm+9cm+3cm+3cm = 24cm if you have a box that is 9cm long and 3cm wide then you would say width + length + width + length because the side opposite from 3cm is also 3cm and the side opposite 9cm is also 9cm. so you would add: 9cm+9cm+3cm+3cm = 24cm
