To determine how many 1-inch squares Anna can cut from the cereal box, we first need to calculate the volume of the rectangular prism shaped cereal box.
The volume \( V \) of a rectangular prism is given by the formula:
\[ V = \text{length} \times \text{width} \times \text{height} \]
Given the dimensions of the box:
- Length = 10 inches
- Width = 4 inches
- Height = 12 inches
Now, we calculate the volume:
\[ V = 10 , \text{in} \times 4 , \text{in} \times 12 , \text{in} = 480 , \text{cubic inches} \]
Since each small square has an area of \( 1 , \text{in}^2 \) (since it is 1 inch by 1 inch), we can conclude that the number of 1-inch squares that can be cut from the box is equal to the volume in cubic inches.
Thus, Anna can cut out:
\[ 480 \text{ squares} \]
However, there is no "480 squares" option in your list of responses. It appears there might be a misunderstanding regarding the choices. Based on the calculation:
Total number of squares = 480 squares
