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

Dear Student,

Volume of earth dug out = Volume of pit = Length * Breadth * Width =  2 * 1.5 * 80 = 240 m³

Height of the dug out earth material when spread on the platform = 15 cm = 0.15 m
Length of the dug out earth material when spread on the platform = 12 .5 m

Volume of the dug out earth material = 240 m³
0.15 * 12.5 * Width = 240

$Width = \frac{240}{0.15 * 12.5} = 128 m$

Width of the dug out earth material when spread on the platform = 128 m
