To calculate the volume of a rectangular prism, you can use the formula:
\[ \text{Volume} = \text{length} \times \text{width} \times \text{height} \]
In your case, it seems you mentioned "8 inches long," "5 inches wide," and "2 inches long." Assuming the third dimension is the height, the dimensions would be:
- Length = 8 inches
- Width = 5 inches
- Height = 2 inches
Now plug in the values:
\[ \text{Volume} = 8 , \text{inches} \times 5 , \text{inches} \times 2 , \text{inches} \]
\[ \text{Volume} = 80 , \text{cubic inches} \]
So, the volume of the rectangular prism is 80 cubic inches.
