Help with calculation step by step to get answer.?

mass density =2.95*10^-4 kg/m 

 wavelength = 2 × 1.2/2 = 1.2 m 

 Frequency = 1/ λ(T/m)^1/2 = 

 How do I calculate this step by step:

 120*1.2=(T/2.95*10^-4)^1/2

    mass density would be in kg/m²

    yes, 2 x 1.2/2 = 1.2, what is your point?

    Frequency = 1/ λ(T/m)^1/2

    What is T ? have not seen this formula before...

    just from units, we have

       1/sec = 1 / meters√(T/kg)

       meters√(T/kg) = sec

       √(T/kg) = sec/meters

       T/kg = s²/m²

       T = kg•s²/m² ?? unknown

    finally, what do you want to calculate. Perhaps T ?

    120*1.2=(T/2.95*10^-4)^1/2

    144 = √(T/0.000295)

    T/0.000295 = 144² = 20736

    T = 20736 • 0.000295 = 6.117 kg•s²/m²

      (have no idea what the units actually are)
