A carpenter will make a single, straight cut through the rectangular prism shown below by
randomly choosing a face and cutting parallel to that face. The cut will be a whole number of
centimeters from the chosen face.
8 cm
4 cm
25 cm
What is the probability that the area, in square centimeters, of the cross section created by
the cut will not be a multiple of 100?
A. 0
B. 1/3
C.2/3
D.1

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.
