The volume of a rectangular parallelepiped is 3.15 m3, length 3.75 m and width 6 dm. Find its height.

We translate the known value of the width of the rectangular parallelepiped from decimeters to meters.

Since there is 10 dm in 1 meter, we get:

6 dm = 6/10 = 0.6 m.

Determine the area of the base of the rectangular parallelepiped.

To do this, we multiply its length and width among ourselves.

Will be:

3.75 * 0.6 = 2.25 m2

Find the height of the figure.

To do this, we divide the known volume of the parallelepiped by the found area of the figure.

We get:

3.15 / 2.25 = 1.4 m.

Answer: The height of the parallelepiped is 1.4 m.
