to solve this I'll justt convert the cm to mm..

there are 10 mm in 1 cm if I'm not mistaken

so
first icicle
27 cm = 27(10)mm = 270 mm....+ 3 mm more is 273 mm total...

11cm = 11(10)mm = 110mm..... + 7mm more is 117 mm total

so now subtract them

273mm - 117mm is 

156mm

now to convert that to cm....divide by 10

156 mm = 156/10 cm = 15 cm and 6 mm
