The dimensions of an oil tin are 26 cm x 26 cm x 45 cm. Find the area of tin sheet required to make 20 such tins.
Answers
Step-by-step explanation:
Length of an oil tin = 26cm
Breadth of an oil tin = 26cm
Height of an oil tin = 45cm
Firstly, we will find the area of tin required for the sheet using the formula of total surface area of cuboid.
Total surface area of cuboid =2(length×breadth+breadth×height+length×height)
Area of an oil tin required for sheet =2[26×26+26×45+26×45]cm2
So the area of tin sheet required for making 20 sheets =40[26×26+26×45+26×45]cm2
=120640cm2
Converting cm2 into m2.
=120640100×100m2
Now we will find the cost of tin used for making 20 such tins when 1 square meter of the tin sheet cost R.s. 10 =120640100×100×10
=12064100
= R.s. 120.64
Therefore, the area of the tin sheet required for making 20 oil tins is 120640cm2 and the cost of tin used for 20 oil tins is R.s. 120.64.
