Aright rectangular prism has a length of 12 ft, width of 5/12 ft, and height of 10 1/12 ft. what is the volume of the prism?

Mult. these 3 dimensions together to obtain the volume of the prism:

(12 ft)(5/12  ft)(10   1/12  ft).  Expressing all of these factors as improper fractions, we get:

  12        5       121        5(121) ft^3
* * = = 50.42 ft^3 = volume of the prism
    1       12       12             12

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
