# Find the volume of a rectangular parallelepiped if its width is 1.6dm, its length is 1.5 times

Find the volume of a rectangular parallelepiped if its width is 1.6dm, its length is 1.5 times its width, and its height is 0.7dm less than its width.

The volume of a rectangular parallelepiped is 3.46 dm³.
1. Find the length of the rectangular parallelepiped, which is 1.5 times the width:
1.6 * 1.5 = 2.4 dm.
2. The height of the rectangular parallelepiped is 0.7 dm less than the width. Let’s find it:
1.6 – 0.7 = 0.9 dm.
The volume of a rectangular parallelepiped is calculated as the product of all three of its dimensions (length, width and height):
2.4 * 1.6 * 0.9 = 3.456 dm³.
Let’s round the resulting volume value to hundredths. According to the rules of rounding, we must round up the hundredths. We get: 3.46 dm³.
