Answer 1

Answer:

Length of sheet, l = 4.234 m Breadth of sheet, b = 1.005 m Thickness of sheet, h = 2.01 cm = 0.0201 m The given table lists the respective significant figures: Hence, area and volume both must have least significant figures i.e., 3. Surface area of the sheet = 2 (l × b + b × h + h × l) = 2(4.234 × 1.005 + 1.005 × 0.0201 + 0.0201 × 4.234) = 2 (4.25517 + 0.02620 + 0.08510) = 2 × 4.360 = 8.72 m2 Volume of the sheet = l × b × h = 4.234 × 1.005 × 0.0201 = 0.0855 m3 This number has only 3 significant figures i.e., 8, 5, and 5.Read more on Sarthaks.com - https://www.sarthaks.com/34908/the-length-breadth-and-thickness-rectangular-sheet-of-metal-are-234-005-and-respectively
