The height of the rectangular parallelepiped is 7 decimetres, the width is 1 dm less

The height of the rectangular parallelepiped is 7 decimetres, the width is 1 dm less, and the length is 2 times the width. Find the volume of the parallelepiped

Let’s find the dimensions of a rectangular parallelepiped if the relationships between them are known:

1) 7 – 1 = 6 (dm) – the width of the parallelepiped

2) 6 * 2 = 12 (dm) – figure length

Volume is found as the product of length, width and height: V = a * b * c. We get:

3) 7 * 6 * 12 = 504 (dm3).

Answer: the volume of a rectangular parallelepiped is 504 dm3.
