(12 x 4) x 3
(You do not need the brackets)
(2^4 x 3^2)
(This is what I used)
8 x 2 x 9
3 x 6 x 8
In the integers:
length × width × height = 1×48×3, 2×24×3, 3×16×3, 4×12×3 and 6×8×3, as well as all their permutations.
In the rational numbers, there are an infinite number of solutions. The height has to be 3, because volume = base * height => 144 = 48 * h, but the rectangle that is the base with an area of 48 square units can have any length a and width b = 48/a.
