This may helo u to solve the upper question

they both r most similar

Answer 2

Surface area of a cuboidal hall without bottom = Total surface area – Area of base

= 2 [lb + bh + hl] – lb

= 2 [15 × 10 + 10 × 7 + 7 × 15] – 15 × 10

= 2[150 + 70 + 105] – 150

= 2 [325] – 150

= 650 – 150

= 500 m2

Area of the paint in one can = 100 m2

Number of cans required = 500100 = 5 cans.
