Question

three cubes of sides 6cm,8cm,1cm are melted to form a new cube then the length of the edge of new cube ______cm​

Answer 1

Sides of three cubes = 6cm , 8cm and 1cm .

Volume of cube = a³

Total Volume of the three cubes

$= {6}^{3} + {8 }^{3} + {1}^{3} \\ =21 6 + 512 + 1 \\ = 729$

Volume of big cube = 729cm³

$side = \sqrt[3]{729} \\ \: \: \: \: \: \: \: \: \: \: = 9cm$

Therefore the the length of edge of new cube is 9cm.
