Need help solving this question, please?

What is the acoustic impedance of the following materials?

(where c is the speed of sound in that material)

(a) air: p = 1.2 kg/m3

            c = 343 m/s

(b) concrete p = 2400 kg/m3

                    c = 3400 m/s

    Z = ρ c

    So just multiply density and sound speed for each material.

    c is 42kg/m3 that is the awnser
