How many bags of grain can be stored in a cuboidal granary (8 m × 6 m × 3 m),

(d) 225

Volume of the cuboidal granary $=(8 \mathrm{~m} \times 6 \mathrm{~m} \times 3 \mathrm{~m})$

Volume of each bag $=0.64 \mathrm{~m}^{3}$

Number of bags that can be stored in the cuboidal granary $=\frac{\text { Volume of the cuboidal granary }}{\text { Volume of each bag }}$

$=\left(\frac{8 \times 6 \times 3}{0.64}\right)$

$=225$
