Total Surface area of the Tank = 2(lb + bh+ hl)
= 2(20*12 + 12*8 + 8*20 )
= 2( 240 + 96 + 160 )
= 2 * 496
= 992 m sq.
Length of the sheet required = Area / Breadth
= 992 / 2.5
= 396.8 m
Now, Cost of the sheet = 396.8 * 12.50
= Rs. 4960

total surface area of the tank = 2(length*breadth + breadth*height+ height*length)
= 2(20*12 + 12*8 + 8*20 )
= 2( 240 + 96 + 160 )
= 2 * 496
= 992 metre square
length of sheet required = Area / Breadth
= 992 / 2.5
= 396.8 m
cost of sheet = 396.8 * 12.50 = Rs. 4960
done its confusing tough
