You use the superscript 2 or 3.
Thus 832 or 833. If you cannot use superscripts (as in the browser used for posting questions here), spell it out - just as you did.
8 cubed in standard form is 83
42/23
2/4
2 squared --> 4 2 cubed --> 8 3 squared --> 9 3 cubed --> 27
pi squared is 9.869604401... pi cubed is 31.00627668
The volume is cubed and the surface area is squared.
Neither!!! Perimeter is the addition of all the straight lines that form the perimeter.
A squared X a = a cubed. Algebraically, a^(2) X a = a^(3)
Remember a straight line is NOT 'powered/indexed'. a^(1) or just 'a' For Area , the power/index is 'squared' . a^(2) For Volume, the power/index is 'cubed' a^(3)
Squared means 2 in exponents and cubed means 3 in exponents. For example, It saids 5 cubed, than it would be 5.3 .
32 + 63 = 9 + 216 = 225
83 = 8 x 8 x 8 = 512
