Question

A beam 9 m long, 50 cm wide, and 20 cm deep is made of wood which weighs 30 kg per m, tind
weight of the beam​

Answer 1

Step-by-step explanation:

Length of beam(l)=9 m

Length of beam(l)=9 m Breadth of beam(b)=50 cm

Length of beam(l)=9 m Breadth of beam(b)=50 cm =0.5 m

Length of beam(l)=9 m Breadth of beam(b)=50 cm =0.5 m Depth of beam(h)=20 cm

Length of beam(l)=9 m Breadth of beam(b)=50 cm =0.5 m Depth of beam(h)=20 cm =0.2 m

Length of beam(l)=9 m Breadth of beam(b)=50 cm =0.5 m Depth of beam(h)=20 cm =0.2 m Volume of beam=lbh

Length of beam(l)=9 m Breadth of beam(b)=50 cm =0.5 m Depth of beam(h)=20 cm =0.2 m Volume of beam=lbh = 9×0.5×0.2 m³

Length of beam(l)=9 m Breadth of beam(b)=50 cm =0.5 m Depth of beam(h)=20 cm =0.2 m Volume of beam=lbh = 9×0.5×0.2 m³ =0.9 m³

Length of beam(l)=9 m Breadth of beam(b)=50 cm =0.5 m Depth of beam(h)=20 cm =0.2 m Volume of beam=lbh = 9×0.5×0.2 m³ =0.9 m³ Given,

Length of beam(l)=9 m Breadth of beam(b)=50 cm =0.5 m Depth of beam(h)=20 cm =0.2 m Volume of beam=lbh = 9×0.5×0.2 m³ =0.9 m³ Given, weight per cubic metre=30 Kg

Length of beam(l)=9 m Breadth of beam(b)=50 cm =0.5 m Depth of beam(h)=20 cm =0.2 m Volume of beam=lbh = 9×0.5×0.2 m³ =0.9 m³ Given, weight per cubic metre=30 Kg weight for 0.9 m³=0.9×30

Length of beam(l)=9 m Breadth of beam(b)=50 cm =0.5 m Depth of beam(h)=20 cm =0.2 m Volume of beam=lbh = 9×0.5×0.2 m³ =0.9 m³ Given, weight per cubic metre=30 Kg weight for 0.9 m³=0.9×30 =27 Kg

Length of beam(l)=9 m Breadth of beam(b)=50 cm =0.5 m Depth of beam(h)=20 cm =0.2 m Volume of beam=lbh = 9×0.5×0.2 m³ =0.9 m³ Given, weight per cubic metre=30 Kg weight for 0.9 m³=0.9×30 =27 Kg

Length of beam(l)=9 m Breadth of beam(b)=50 cm =0.5 m Depth of beam(h)=20 cm =0.2 m Volume of beam=lbh = 9×0.5×0.2 m³ =0.9 m³ Given, weight per cubic metre=30 Kg weight for 0.9 m³=0.9×30 =27 Kg Hope it helps u :-)

Answer 2

Answer:

Hope this helps!!!  Please follow me

Step-by-step explanation:

Length of beam(l)=9 m

Breadth of beam(b)=50 cm

                              =0.5 m

Depth of beam(h)=20 cm

                           =0.2 m

Volume of beam=lbh

                         = 9×0.5×0.2 m³

                         =0.9 m³

Given,

weight per cubic metre=30 Kg

weight for 0.9 m³=0.9×30

                          =27 Kg
