A certain encyclopedia has 20 volumes, each of which is w inches wide, k inches long and t inches thick. If all of the volumes are to be tightly packaged in one rectangular box that is k inches wide and w inches deep inside, could the inside length of the box less than 35 inches

(1) t = 1.5

(2) w=9 and k=12

you should think about it like is T * 20 < 35

statement 1 tells us that t=1.5 so 1.5 * 20 < 35 so 30<35 suffiecint

statement 2 tells us nothing about about T so in sufficient

the answer is A
