The volumes of 3 solid cubes made of metal are $125 cm^3, 64 cm^3$ and $27 cm^3$ respectively. After melting all the three cubes a solid cube is made. Find the edge of the new cube.
Answer & explanation
Correct answer: option 3
Volume of the new cube formed = 125 + 64 + 27 = 216 cm³
We know,
Volume = ( Side )³
( Side )³ = 216
( Side )³ = 6³
So, Side = 6 cm
