Correct Answer: 1674 cm 3


Solution : The volume of a cube = (Side) 3
The volume of the first cube = 7 3 = 343 cm 3
The volume of the second cube = 11 3 = 1331 cm 3
When the two cubes are melted and formed into a single cube, the volume of the new cube is the sum of the volumes of the original cubes = 343 + 1331 = 1674 cm 3
Hence, the correct answer is 1674 cm 3 .
