Let the sides be length(L),width(W) and height(H), so L+W+H = 6.
Area of cuboid = 2(LW + WH LH).
How many Integer solution is possible for L,W,H that satisfies L + W + H =6
There are just 3 {1,2,3},{1,1,4},{2,2,2}
Use this to calculate the area and we can see it's always less than 25.
So quantity B is larger. Answer is B)
