Find the volume of a rectangular parallelepiped using the formula V = ABC, if a = 2.81 b = 1.76 c = 4.9 dm.

1. To solve this problem, we need knowledge of the following formulas:

The volume of a rectangular parallelepiped is equal to the product of its length, width and height.

V = a * b * c;

2. Now let’s find the volume of a rectangular parallelepiped for this, substitute the quantities known to us, such as a = 2.81 dm, b = 1.76 dm, c = 4.9 dm into the formula for the volume of a rectangular parallelepiped, then we get:

V = a * b * c = 2.81 dm * 1.76 dm * 4.9 dm = 24.23 dm ^ 3.

Answer: The volume of a rectangular parallelepiped is 24.23 dm ^ 3.
