The length of the rectangular parallelepiped is 80 cm, its height is 45% of the length, and the width is 1 8 \ 27 times the height.

The length of the rectangular parallelepiped is 80 cm, its height is 45% of the length, and the width is 1 8 \ 27 times the height. Calculate the volume of a parallelepiped?

To find the percentage of the number, you need to multiply this number by the desired percentage and divide by 100.
1) Find the height of the parallelepiped:
80 * 45: 100 = 36 (cm) – height.
2) Determine the width of the parallelepiped:
36 * 1 8/27 = 36/1 * 35/27 = 46.7 (cm) – width.
The formula for finding the volume of a rectangular parallelepiped:
V = a * b * c, a – length, b – width, c – height of a parallelepiped.
3) Find the volume of the parallelepiped:
80 * 36 * 46.7 = 134 496 (cm ^ 3).
Answer: the volume of a parallelepiped is 134,496 cm ^ 3.
