Question

How many bags of grain can be stored in a cuboidal granary (8 m × 6 m × 3 m), if each bag occupies a space of 0.64 m³?
(a) 8256
(b) 90
(c) 212
(d) 225

Answer 1

(d) 225
Volume of the cuboidal granary$=\left(8\text{m}\times 6\text{m}\times 3\text{m}\right)$
Volume of each bag$=0.64{\text{m}}^3$

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
