Question

a beam 11m long 40 cm wide and 30 cm deep is made of wood which wieghs 25 kg per m3 . find the weight of the beam

Answer 1

Answer:

33

Step-by-step explanation:

Length of beam(l) = 11 m

Breadth of beam(b) = 40 cm

                              = 0.4 m

Depth of beam(h) = 30 cm

                             = 0.3 m

Volume of beam= l x b x h

                         = 11 × 0.4 × 0.3 m³

                         = 1.32 m³

Given,

Weight per m³ = 25 Kg

Weight for 1.32 m³= 1.32 × 30

                          = 33 Kg
