Answer:

81mm

Step-by-step explanation:

the number of steps is small enough that we can simply list out each step

let the time elapsed be t and the original length be L ( = 1 mm)

when t = 0, L = 1mm

when t = 10, L = 3mm

when t = 20, L = 3 x 3 = 9mm

when t = 30, L = 9 x 3 = 27mm

when t = 40, L = 27 x 3 = 81mm
