Find the volume of a rectangular parallelepiped if its length is 2.3, width is 1.4, and height is 0.5.

Answer: the volume of this rectangular parallelepiped is 1.61 cm³.

Since the opposite edges of a rectangular parallelepiped are equal to each other, then to determine its volume, it is enough to have the values of its three dimensions: the length of the base, the width of the base and the height of the parallelepiped. All the necessary values are present in the conditions of the problem. The volume of a rectangular parallelepiped will be calculated as the product of all three specified dimensions:

2.3 * 1.4 * 0.5 = 1.61 cm³.
