we have to find surface area of cuboid shaped go down
surface area=lb+bh+lh
=(50×40) +(40×10)+ (50×10)
=2000+400+500
=2900 m²
cost = 2900×20
=Rs 58000
surface area=lb+bh+lh
=(50×40) +(40×10)+ (50×10)
=2000+400+500
=2900 m²
cost = 2900×20
=Rs 58000

The Godown is a closed cuboid of L=50m W=40m H=10m we therefore get the total surface area of the godown:(2*50*40)+(2*40*10)+(2*50*10)=5800m2.
1m2=rupee 20
Therefore:20*5800=116000
Rupee116000
1m2=rupee 20
Therefore:20*5800=116000
Rupee116000
