    In case you still can't get the answer. It's 2 rectangular prisms.

    Reasoning being:

    Imagine a cube with all height, width and depth of 4. The volume would be equal to 4x4x4=64

    now if you cut that cube in half, you get a volume of 32 or.. 4x4x2. That area is not cubic (cubic areas are always x^3). So it must be rectangular
