Question

The length, breadth and thickness of a rectangular sheet of metal are $4.234	ext{ m}$, $1.005	ext{ m}$, and $2.01	ext{ cm}$ respectively. What is the volume of the sheet to correct significant figures?

Professor PC Thomas Classes · Answer

$l = 4.234	ext{ m}$ (4 sig figs), $b = 1.005	ext{ m}$ (4 sig figs), $t = 2.01	ext{ cm} = 0.0201	ext{ m}$ (3 sig figs). Volume $= l 	imes b 	imes t = 0.0855289	ext{ m}^3$. The result should be rounded to 3 significant figures. Thus, $0.0855	ext{ m}^3$.
