Question

A beam 9 long, 50 cm wide and 20 cm deep is made of wood which weighs 30kg per m^3, find weight of beam

Answer 1

Volume of Beam = LBH = 9 * 50 * 20

= 9000 cm ³ = 9000 / 1000000 = 0. 09 m ³

1 m ³ = 30 kg

0.09 m ³ = 30 * 0.09 kg

= 30 * 0.09 * 1000 grams

=30 * 9 * 1000 / 100 = 2700 grams

OR 2 . 7 KG
