The dimensions of an iron box are 9ft * 4.4ft* 2.5ft. What is the cost of the iron sheet used to make the box, if the cost of the sheet is rs 6 per square foot?

Answer 1

Answer ⤵️

To find out the cost of the sheet = Surface area of the iron box ×Cost of the sheet per square foot.

Surface area of the iron box= 2(lb+bh+lh)

= 2[ (9×4.4)+(4.4×2.5)+(9×2.5)]

= 2(39.6+11+22.5)

= 2×73.1

= 146.2 ft³

Cost of the sheet= 146.2×6

= ₹877.2

So, the cost of the sheet is ₹877.2
