A cuboidal oil tin is 35cm X 40cm X 50cm. Find the cost of the tin required for making 50 such tins if the cost of tin sheet is Rs. 45/m2.
Answers
Answer:
Step-by-step explanation:
Length=35cm
Breath=40cm
Height=50cm
Area of 1 tin=2(LB+BH+HL)
=2(35×40+40×50+50×35)
=2 (1400+2000+1750)
=2 (5150)
=10300cm^2
Area of 50 such tin =50×10300
=515000cm^2
=51.5m^2
Cost of 1m^2=Rs45
Cost of 51.5m^2=45×51.5
=Rs2317.5
Answer:
Rs 2317.5
Step-by-step explanation:
First we fill find the surface area of a cuboid oil Tin
= 2 × ((35 × 40) + (35 × 50) + (40 ×50))
= 2 × ( 1400 + 1750 + 2000)
= 2 × 5150
= 10300 cm²
1cm = 1/100 m
1/cm² = 1/100² m²
1/cm² = 1/10000 m²
Surface Area = 10300/10000 m²
= 1.03 m²
Tin Sheet required to make one box = 1.03 m²
Tim Sheet required to make 50 boxes = 50 × 1.03 = 51.5 m²
Tin Sheet Cost = Rs 45 /m²
Cost = 51.5 × 45 Rs
= Rs 2317.5
