question about dead loads

[PhysicsApprentice]

density = 1000
volume = 0.6 x 0.020 x 1.0
answer = 0.6 x 0.020 x 1000 x 10 = 120N/m

can someone plz explain to me why you have to times it by 10 at the end to get 120n/m

i understand the equation just dont understand the x 10 part at the end.

Try writing down the units as well. You may see the answer easier. And also take into consideration that g is often given as 10m/s^2.
