Checking force exercice

1. The problem statement, all variables and given/known data

Here is the statement :
An elevator cabin of mass 567 kg combine a mass of people inside the cabin of 180 kg.The cabin is pulled upward by a cable with a constant acceleratuon of 6 m/s².
What is the tension T of the cable

2. Relevant equations

I used the second law of Newton :
Fnet = ma
with m = 567 + 180 = 747
3. The attempt at a solution

so T+ Fg = ma
and T= ma+ mg
so T= 11810.07 N
