The length of a straight parallelepiped is 80 cm. Its width is 3/5 of its length

The length of a straight parallelepiped is 80 cm. Its width is 3/5 of its length, and its height is 40% of its length. Calculate the volume of the parallelepiped.

According to the condition of the problem, a rectangular parallelepiped is given, the length of which is 80 centimeters.

Let’s calculate what its width is equal to, which is 3/5 of the length:

80 * 3/5 = 240/5 = 48 centimeters.

Let’s calculate the height of the parallelepiped, given that it is 40% of the length:

80 * 40% = 80 * 0.4 = 32 centimeters.

Let’s find what the volume of this parallelepiped is equal to:

V = a * b * c.

V = 80 * 48 * 32 = 122880 cm³ = 122.88 dm³.

Answer: the volume of a parallelepiped is 122880 cm³ or 122.88 dm³.
