Find the volume of the cuboid in each of the following cases.

a) The base has one side of [[$ 12 \;\text{cm} $]], the other side is [[$ 3 \;\text{cm} $]] longer, and the height is [[$ 4 \;\text{cm} $]].

Answer: The volume of the cuboid is cm [[$ ^3 $]].

b) The area of the base is [[$ 40 \;\text{cm}^2 $]] and the height is [[$ 6 \;\text{cm} $]].

Answer: The volume of the cuboid is cm [[$ ^3 $]].

c) The area of the top is [[$ 30 \;\text{cm}^2 $]] and the depth is [[$ 4 \;\text{cm} $]].

Answer: The volume of the cuboid is cm [[$ ^3 $]].
