Answer 2

Answer:

36 kg

Step-by-step explanation:

Length of beam = 9 m.

Breadth of beam = 40 cm = 0.4 m.

Height of beam = 20 cm = 0.2 m.

Volume of beam = Length * Breadth * Height

                            = 9 * 0.4 * 0.2

                            = 0.72 m³

                            = 0.72 * 50

                            = 36 kg

Hope it helps!
