| Area is the product of width and length. We know that this value for a rectangular parallelepiped is 12 cm² and width = 3 cm. Let us express the unknown side:

a = S: b = 12: 3 = 4 cm.

The height of such a figure = 2 cm.

The volume is calculated using the formula:

V = a * b * c = 4 * 3 * 2 = 24 cm³.

The perimeter is the sum of all edges, we find it by the formula:

L = 4 * (a + b + c) = 4 * (4 + 3 + 2) = 4 * 9 = 36 cm.
