Find the volume of a rectangular parallelepiped, the length of which is 6 dm, the width is 4 dm, and the height is 3 dm.

1. From the data presented in the problem statement, we know that the length of the rectangular parallelepiped is 6 dm.

2. Also, according to the condition of the problem, the width of the rectangular parallelepiped is 4 dm.

3. Let’s define what the volume of a given rectangular parallelepiped is equal to if its height is 3 dm. To do this, we need to find the product of all three dimensions of a given parallelepiped.

6 * 4 * 3 = 72 dm ^ 3.

Answer: The volume of a given rectangular parallelepiped is 72 dm ^ 3.
