Question

A pit 2m*1.5m*80m was dug. The dug out earth was evenly spread at 15cm height on a platform. If the length of platform was 12.5 long,find it's width

Answer 1

$volume \: of \: earth \: dug \: out = volume \: of \: platform \\ 2m \times 1.5m \times 80m = 15cm \times 12.5m \times width \\ 2m \times 1.5m \times 80m = \frac{15}{100} m \times 12.5m \times width \\ width = \frac{2 \times 1.5 \times 80 \times 100}{15 \times 12.5} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: = 2 \times 16 \times 4 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: = 128m$
