The problem asks us to find the volume of a rectangular prism with length 4 mm, width 3 mm, and height 1 mm. The answer should be in cubic millimeters.

1. Problem Description

The problem asks us to find the volume of a rectangular prism with length 4 mm, width 3 mm, and height 1 mm. The answer should be in cubic millimeters.

2. Solution Steps

To find the volume of a rectangular prism, we use the formula:

$Volume = length \times width \times height$

Given the dimensions:

Length = 4 mm

Width = 3 mm

Height = 1 mm

Plugging these values into the formula:

$Volume = 4 mm \times 3 mm \times 1 mm$

$Volume = 12 mm^2 \times 1 mm$

$Volume = 12 mm^3$

3. Final Answer

The volume of the rectangular prism is 12 cubic millimeters.
