How many bags of grain can be stored in a cuboid granary 12 m × 6 m × 5 m. If each bag occupies a space of 0.48 m³?
Answer: A
Divide the granary's volume by the space one bag needs.
\[ V = 12 \times 6 \times 5 = 360 \text{ m}^{3} \]
\[ n = \frac{360}{0.48} = 750 \]
The division by a decimal is where slips creep in: \( \tfrac{360}{0.48} = \tfrac{36000}{48} = 750 \), which is cleaner to compute after multiplying both numbers by 100.
