Hello all,
This question in OG 12 is pretty ambigous.
122. What is the volume of a certain rectangular solid?
(1) Two adjacent faces of the solid have areas 15
and 24, respectively.
(2) Each of two opposite faces of the solid has
area 40.
which two opposite faces does the 2nd statement refer to? By the wording used in statement I thought that l*b=40, b*h= 40, and h*l=40. So, i thought side must be square root of 40. But, OG answer takes the other face(other than 15 and 24) and its oppsite face to be of area 40 and says C is the right answer. Isnt it wrong to assume the other face to be of area 40???
