The formula for the volume of a box is V=1· w ·h, Where 1 is the length, w is the width, and h is height. Using rounding to the nearest whole number, which of the following is an estimate of the volume of a box that has a length of a 7.2 centimeters, a width of 6.1 centimeters, and a height of 8.9 centimeters?A.) 218 cmB.) 242 cmC.) 378 cmD.) 452 cm

Answer:C)  The estimated volume of the box  is 378 sq cm.Step-by-step explanation:Here, length of the box  =  7.2 cmWidth of the box  = 6.1 cmHeight of the box  =  8.9 cmNow, if the number is of the form a.b If b  <  5, the number is rounded off to a. If b ≥  5, the number is rounded off to (a+1).Hence, 7.2 is rounded off to  7.  (as 2< 5)  ⇒ L'  = 7 cm             6.1 is rounded off to 6. (as 1< 5)   ⇒  W'  = 6 cm             8.9 is rounded off to 9.  (as 9 > 5) ⇒ H'  = 9 cmNow, the volume of the box = L'x B' X H' = 7 cm x 6 cm x 9 cm = 378 sq cmHence, the estimated volume of the box  is 378 sq cm.
