To find the volume of a rectangular prism, you can use the formula:
\[ \text{Volume} = \text{length} \times \text{width} \times \text{height} \]
In this case, the dimensions are:
- Length = 9 mm
- Width = 4 mm
- Height = 19 mm
Now, substitute the dimensions into the formula:
\[ \text{Volume} = 9 , \text{mm} \times 4 , \text{mm} \times 19 , \text{mm} \]
Calculating this step by step:
- \(9 \times 4 = 36\)
- \(36 \times 19 = 684\)
So, the volume of the rectangular prism is:
\[ 684 , \text{mm}^3 \]
The correct response is 684 mm³ (or 684 mm cubed).
