Given:

l = 86.4 centimeters – the amount by which bamboo grows in one day;

t1 = 1 second – time interval;

t2 = 1 year – time span ..

It is required to determine l1 and l2 (meters, centimeter, millimeter) – how much the bamboo will grow during the time intervals t1 and t2.

Let’s calculate the growth rate of bamboo:

v = 86.4 centimeters / day = 0.864 meters / day = 0.00001 meters / second.

Then in 1 second it will grow by:

l1 = v * t1 = 0.00001 * 1 = 0.00001 meter = 0.001 centimeter = 0.01 millimeter.

Taking into account the fact that 1 year = 365 days, in one year bamboo will grow by the amount:

l2 = v * t2 = 0.864 * 365 = 315.36 meters = 31536 centimeters = 315360 millimeters.

Answer: in one second, bamboo will grow by 0.00001 meters (0.001 centimeters = 0.01 millimeters), in one year – by 315.36 meters (31536 centimeters = 315360 millimeters).
