In a rectangular parallelepiped, the length is 1.2 m, the width is 3 times less than the length

In a rectangular parallelepiped, the length is 1.2 m, the width is 3 times less than the length, and the height is 0.2 m more than the width. Find the volume.

By the condition of the problem, a rectangular parallelepiped is given.

It is known that the length of this parallelepiped is 1.2 meters.

Let’s calculate what the width of the parallelepiped is, given that it is 3 times less than its length:

b = a / 3 = 1.2 / 3 = 0.4 m.

Let’s calculate the height of the parallelepiped, which is 0.2 meters more than the width:

c = b + 0.2 = 0.4 + 0.2 = 0.6 m.

Let’s calculate the volume of the parallelepiped:

V = a * b * c = 1.2 * 0.4 * 0.6 = 0.288 m³.

0.288 m³ = 288 dm³.

Answer: a parallelepiped has a volume equal to 0.288 m³ or 288 dm³.
