Step-by-step explanation:
Dimension of the cuboidal container =50cm×40cm×30cm
Tin sheet used to manufacture the cuboid=Total surface area of the cuboid
∴ Total surface area of the cuboid=2(lb+bh+lh)
=2(50×40+40×30+30×50)=2(2000+1200+1500)=2×4700=9400m
2
∴Tin sheet used to manufacture the cuboidal container is 9400m
2
It is required to make 10 such containers.
∴ Tin sheet required to make 10 such containers=9400×10=94,000cm

Price of tin sheet per sq.m=Rs.20
Price of tin sheet to make 94,000cm
