The volume of the rectangular prism is 24 cubic units.
How to calculate volume of a prism.
The volume V of a rectangular prism is given by the product of its length l, width w, and height h.
V = l* w *h
The base of the rectangular prism is made up of (12) unit cubes.
Since the base is made up of unit cubes, we can arrange them in a (3 * 4) → (3 cubes in length and 4 cubes in width).
The rectangular prism has (2) layers 12 unit cubes, so the height is (2).
V = 3 *4 * 2 = 24 cubic units.
Therefore, the volume of the rectangular prism is 24 cubic units.
