Question

a pit 8m long 5m broad 1.5m deep in the ground the soil so dug is evenly spread over a recttangular plot 25m long 16m broad findthe layer of the soil spread over the rectangular plot?​

Answer 1

$volume \: of \: pit = \frac{8 \times 5 \times 15}{10} = 60 \: {m}^{2}$

Now, (25 × 16) × H = 60

$h = \frac{60}{16 \times 25} = \frac{60}{400} = \frac{3}{20} = 0.15m$
