| **The length of a rectangular parallelepiped is 4 dm, its width is 1/2 of its length, and its height is 3/4 times less than its width. find the volume**

1) Calculate the width of a rectangular parallelepiped, provided that it is ½ of its length, equal to 4 dm:

b = 4: 2 = 2 dm.

2) The height is ¾ times less than b:

2: ¾ = 8/3 or 2 2/3 dm.

3) The volume of such a figure is calculated by the formula:

V = a * b * c = 4 * 2 * 8/3 = 21 1/3 dm³.
