The dimensions of an oil tin are $26cm \times 26cm \times 45cm$. Find the area of tin sheet required to make 20 such tins.

Given:

 Length of the sheet = 26 cm

Breadth of the sheet  =  26 cm

Height of the sheet  =  45 cm

To do:

We have to the area of the tin sheet required to make 20 such tins.

Solution:

Sheet required to make 1 tin  = Total surface area of the sheet.

Total surface area of sheet = $2(length \times breadth) + 2 (breadth \times height) +

2 (length \times height )$

Total surface area of the sheet = $2 (26 \times 26)  +  2 (26 \times 45)  +  2 (26 \times 45)$

Total surface area of the sheet = $2 (676) + 2 (1170) + 2 (1170)$

Total surface area of the sheet = $1352 + 2340 + 2340$ 

Total surface area of the sheet =  6032 sq cm

Sheet required to make 20 tins  = $20 \times Total surface area of a sheet$

Sheet required to make 20 tins  = $20 x 6032$

Sheet required to make 20 tins  = 120640 sq. cm.
