One edge of a rectangular parallelepiped is 6.8 cm. the second rib is 85% of the first and 40%

One edge of a rectangular parallelepiped is 6.8 cm. the second rib is 85% of the first and 40% of the third. find the volume of this parallelepiped.

The volume is equal to the product of its three sides.
The length of the second edge is:
(6.8cm * 85%) / 100% = 5.78cm;
This edge is 40% of the third, so the third edge is equal to:
(5.78cm * 100% / 40%) = 14.45cm;
The required volume is equal to:
6.8cm * 5.78cm * 14.45cm = 567.9428cm ^ 3.
