To find out how many 1-inch squares Anna can cut from the cereal box, we first need to calculate the volume of the rectangular prism (cereal box) using the formula:
\[ \text{Volume} = \text{length} \times \text{width} \times \text{height} \]
Given the dimensions:
- Length = 10 inches
- Width = 4 inches
- Height = 12 inches
Calculating the volume:
\[ \text{Volume} = 10 , \text{in} \times 4 , \text{in} \times 12 , \text{in} = 480 , \text{cubic inches} \]
Since each square has a side length of 1 inch, each square occupies 1 cubic inch of volume. Therefore, the number of 1-inch squares that can be cut from the cereal box is equal to the volume of the box:
\[ \text{Number of squares} = \text{Volume} = 480 \]
However, it appears that none of the provided answer choices reflect the actual calculation. The answer choices you've listed appear to be incorrect based on the calculations here.
The correct answer should be: 480 squares.
