Answer:
72
Explanation:
First, you need to calculate the volume of the box:
2 1/4 × 2 × 2 = 9 (ft³)
Second, calculate the volume of the foam block:
1/2 × 1/2 × 1/2 = 1/8 (ft³)
In the end, get the volume of the box divided to the volume of the foam block:
9 ÷ (1/8) = 72 ( foam blocks)
Conclusion, the answer is 72 foam blocks
