Re: The volume of a rectangular box x inches wide, y inches long, and z in [#permalink]
The volume of a rectangular box x inches wide, y inches long, and z inches high is 108 in3in3. If x≤y≤zx≤y≤z, what is x + yz?

(1) The area of the largest face of the box is 36 in2in2.
(2) The longest edge of the box is 9 inches.


1) Area = 36

hence y*z = 36
and given x*y*z = 108

=> x = 3 and y*z = 36

=> x+yz = 39

2) z= 9

xyz = 108

=> xy = 12

possible values = (2,6) and (3,4)

since two values for x and y are possible

Hence this is Insufficient.

Answer is A
