Need help on lognormal distribution


I'm a newbie here. I need help on how to find mean and standard deviation for a lognormal distribution. I've been searching on the internet but cant find the answer.

Here is my question.

Let say

X = b x c x sqrt(d)

and b is assumed to follow lognormal distribution with mean 1.26 and standard deviation 0.33.

c is a constant which is equal to 1.392

and d is also follow lognormal distribution with mean 0.833 and standard deviation 0.15

so X should also be lognormal distributed right?

My question is what is the mean value and standard deviation of parameter X?

Appreciate if someone can help me here :)
