Geometry

Question Analysis:
This question involves the volume of a rectangular prism and the concept of filling a percentage of that volume using unit volume objects (candies).
The focus is on using volume formulas and proportion.

Key Concept Explanation:
Volume of box = l × w × h
Use 90% of the volume
Divide usable volume by volume of one candy

Step-by-Step Solution:
Volume = 12 × 10 × 8 = 960 cm³
90% = 0.9 × 960 = 864 cm³ usable
Candies = 864 ÷ 2 = 432

Common Mistakes:
Forgetting to apply the 90% factor
Dividing the full volume instead of the partial (filled) volume
