To find the volume of a right rectangular prism, you can use the formula:
\[ \text{Volume} = \text{length} \times \text{width} \times \text{height} \]
For the popcorn box, the dimensions are:
- Length = 9 inches
- Width = 4 inches
- Height = 12 inches
Now, plug in the values:
\[ \text{Volume} = 9 , \text{inches} \times 4 , \text{inches} \times 12 , \text{inches} \]
Calculating that step by step:
- \( 9 \times 4 = 36 \)
- \( 36 \times 12 = 432 \)
So, the volume of the popcorn box is:
\[ \text{Volume} = 432 , \text{cubic inches} \]
Thus, the box can hold 432 cubic inches of popcorn.
