Answer:
I am not sure which numbers should be rounded up, so when it comes to rounding up the diameters of the box, the volume is 378 m^2.
But rounding up from the result of multiplying exact box dimentions, it would be 391 cm^2
Step-by-step explanation:
V = l *w * h
7,2 * 6,1 * 8,9 = 390,88 so rounding up to 391 cm^2
7 * 6 * 9 = 378 cm^2
