Answer: Roughly 8.267*10^6 cubic centimeters

The more accurate answer is 8.266914648*10^6 cubic centimeters

==================================================

Work Shown:


s = 2.022*10^2\\\\v = s^3\\\\v = (2.022*10^2)^3\\\\v = (2.022)^3*(10^2)^3\\\\v = 8.266914648*10^(2*3)\\\\v = 8.266914648*10^6\\\\v \approx 8.267*10^6\\\\

I rounded to three decimal places because the 2.022 is to three decimal places. Round however you need. Or you can choose to leave the number unrounded.

The number 8.267*10^6 is 8,267,000 which is a little over 8.2 million.

The units for the volume are in cubic centimeters, which we can abbreviate as cm^3 or
\text{cm}^3

Note that the value
8.267*10^6 is in the form
A*10^b where
0 \le A < 10, which means this number is in scientific notation form.
