Pythagorean Theorem: a2 + b2 = c2

Step-by-step explanation:

To solve for a, we want to use Pythagorean Theorem as provided int eh problem. a and 2 are the legs while 8 is the hypotenuse.

          [exponent]

           [subtract both sides by 4]

                 [square root both sides]

Now we know that .

6mm^3 or .6cm^3

6     6   6

factor trees are nice.
