heya!
here's ur answer...
volume of the cube(side=2cm)=2×2×2
=8cm³
volume of the cube(side=3cm)=3×3×3
=27cm³
volume of the cube (side=4cm)=4×4×4
=64cm³
therefore volume of the cube which is made after melting them=8+27+64
=99cm³
therefore, the side of new cube=
s×s×s=99cm³
side³=99cm³
side=³√99
side=4.626cm
hope this helps...
