Find the volume, surface area and the sum of the lengths of the edges of a rectangular parallelepiped 4 cm high, 5 cm long, 2 cm wide.

A rectangular parallelepiped is a parallelepiped with all its faces as rectangles.

Provided that its height = 4 cm, length = 5 cm, and width = 2 cm, we find its volume by the formula:

V = a * b * c = 4 * 5 * 2 = 40 cm³.

We calculate the area of the entire surface:

S = 2 * (ab + ac + bc) = 2 * (4 * 5 + 4 * 2 + 5 * 2) = 2 * (20 + 8 + 10) = 2 * 38 = 76 cm².

The length of all ribs is:

L = 4 * (a + b + c) = 4 * (4 + 5 + 2) = 4 * 11 = 44 cm.
