Question

When a cuboid of dimensions 30cm×30cm×42.6cm is melted and converted into cubes of edge 3 cm, the number of cubes formed is​

Answer 1

Answer:

$Given:- \\ </p><p>Dimension \: of \: the \: cuboid \: = \: 30cm*30cm*42.6cm \\ </p><p>So \: , \: volume \: of \: it \: will \: be \: = \: (30*30*42.6)cm^3 \\ </p><p>=38,340cm^3 \\ </p><p>Given:- \\ </p><p>Edge \: of \: each \: cube \: = \: 3cm \\ </p><p>So, \: Volume \: of \: each \: cube \: = \: 3^3cm^3 \\ </p><p>=27cm^3 \\ </p><p>Total \: volume \: that \: had \: melt \: = \: 38,340cm^3 \\ </p><p>Volume \: of \: each \: cube \: =27cm^3 \\ </p><p>Number \: of \: cube \: can \: be \: get \: = \frac{ \: total \: volume}{volume \: of \: each \: cube} \\ </p><p>= \frac{38,340}{27} \\ </p><p>=1420(ans)</p><p>$
