Question

three cubes whose edges measures are 3cm 4cm 5cm respectively are the melted to a single cube find its edge​

Answer 1

Answer:

(3*4*5)3 by this method the answer can come I am not sure

Answer 2

Answer:

$sollution \\ \\ volume \: of \: first \: cube = ({3cm})^{3 } = 27cubic \: cm \\ volume \: of \: second \: cube = {(4cm})^{3} = 64 \: cubic \: cm \\ volume \: of \: third \: cube = {(5cm)}^{3} = 125cubic \: cm \\ \\ vollume \: of \: single \: cube \: after \: melting \\ (27 + 64 + 125)cubic \: cm = 216 \: cubic \: cm \: \\ \\ let \: the \: edge \: of \: new \: cube \: formed \: be \: x \\ {x}^{3} = 216 \\ hence \: x = \sqrt[3]{216} \\ or \: x = 6 \: cm \\ \\ then \: the \: edge \: of \: new \: cube \: formed = 6cn$
