Answer 2

Step-by-step explanation:

let the length of third box is x cm

so, length of first box = (x+10) cm

length of second box = (x-5) cm

total length= 80 cm

x+10+x-5+x=80

3x+5=80

3x=75

x=25

length of first box=(x+10)=35 cm

length of second box=(x-5)=20 cm

length of third box=x = 25 cm
