# Find the volume of a rectangular parallelepiped if a = 1 m b = 2 dm c = 3 cm.

Formula for calculating the volume of a rectangular parallelepiped:
V = a * b * c, where a, b and c are the three dimensions of the parallelepiped (length, height, width).
a = 1 m; b = 2 dm .; c = 3 cm.

1 way.
Let’s convert decimeters and centimeters to meters:
2 dm. = 0.2 m; 3 cm = 0.03 m.
Let’s calculate the volume of the parallelepiped:
V = 1 * 0.2 * 0.03 = 0.006 (m 3).
Answer: the volume of a rectangular parallelepiped is 0.006 m 3.

Let’s convert meters and decimeters to centimeters:
1 m = 100 cm.; 2 dm. = 20 cm.
Let’s calculate the volume of the parallelepiped:
V = 100 * 20 * 3 = 6000 (cm 3).
Answer: the volume of a rectangular parallelepiped is 6000 cm 3.
