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 cm
b.) 242 cm
c.) 378 cm
d.) 452 cm

C)  The estimated volume of the box  is 378 sq cm.

Step-by-step explanation:

Here, length of the box  =  7.2 cm

Width of the box  = 6.1 cm

Height of the box  =  8.9 cm

Now, 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 cm

Now, the volume of the box = L'x B' X H'

= 7 cm x 6 cm x 9 cm

= 378 sq cm

Hence, the estimated volume of the box  is 378 sq cm.
