Question

The number of planks of dimensions (4m x 0.5m x 0.2 m) that can be stored in a pit of dimensions (16 m x 12 m x 4 m) is​

Answer 1

Answer:

Volume of pit = 16×12×4= 768 m³

Volume of each plank = 4×0.5×0.2= 0.4

$no. \: of \: planks \: that \: can \: be \: stored = \frac{ volume \: of \: pit}{volume \: of \: 1 \: plank} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{768}{0.4 } \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \: 1920$

Therefore, 1920 planks can be stored.
