The height of the rectangular parallelepiped is 2 cm, the width is 3 times, and the length is 5 times the height.

The volume of a rectangular parallelepiped can be found using the following formula:

V = abc, where a is the length of the parallelepiped, b is its width, and c is its height.

We know the height. Find the width of the parallelepiped:

b = 3c = 3 * 2 = 6 cm.

Now let’s find the length of the rectangular parallelepiped:

a = 5c = 5 * 2 = 10 cm.

We found all the parameters of this rectangular parallelogram. This means that we can find its volume. Let’s calculate it:

V = 10 * 6 * 2 = 120 cm³.

Answer: the volume of a rectangular parallelepiped is 120 cubic centimeters.
