rectangle.
what volume?
To find the volume of a rectangle, you need to multiply the length, width, and height (since it is a 3D shape).
Given that the measurements are 3cm (length), 12cm (width), and 2cm (height), the volume can be calculated as:
Volume = length x width x height
Volume = 3cm x 12cm x 2cm
Volume = 72 cm^3
Therefore, the volume of the rectangle is 72 cubic centimeters.
