Please help me ​

Answer 1

Answer:

154.8 kg

Explanation:

volume of air = l × b × h

= 8×5×3

= 120 m³

density = mass / volume

1.29 = m/120

1.29×120=m

m= 154.8 kg

Answer 2

process:-

Density=Mass/Volume

D=1.29 kg per metre cube

V=8*5*3=120 metre cube

M=D*V

1.29*120=154.8

mass is 154.8 kg
