7^3 × X^2 = 7 × 7 × 7 × X × X
Seven cubed tells you that 7 is multiplied three time, and the X squared tells you that you multiply X twice.
I have used capital Xs as the times symbol (×) is very similar to a lower case x.
This is why in algebra the times symbol is dropped and any two symbols next to each other are multiplied together, eg 5xy means 5 times x times y and not 5 times y.

The volume is cubed and the surface area is squared.
Neither!!! Perimeter is the addition of all the straight lines that form the perimeter.
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)

2 squared --> 4 2 cubed --> 8 3 squared --> 9 3 cubed --> 27
The result of an exponent is called a product, because it is just repeated multiplication. If an amount is multiplied by itself it is a squared exponent. If that amount is multiplied again by the same amount, it is cubed. If again, it is to the fourth power, and so on. A square square numbers
pi squared is 9.869604401... pi cubed is 31.00627668

A squared X a = a cubed. Algebraically, a^(2) X a = 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
3 cubed = 27 and 9 squared = 81 which is the biggest number
