Let the initial side of the cube be a
Volume = a³
If the side is doubled,
new side = 2a
New Volume = (2a)³
New Volume = 8a³
Let us compare both the volumes :
Initial Volume = a³
New Volume = 8a³
Increase :
Therefore the new volume is 8 times more than the initial volume.
Extras :
Volume of a cuboid = length × breadth × height
Volume of cylinder = π × r²h
Volume of cone =
Volume of sphere =
Volume of hemisphere =
Answer:
8 times
Step-by-step explanation:
Let 'a' be the side of a cube
Therefore, volume of the cube = a × a × a
When side is doubled then each side = 2a
Therefore, volume = 2a × 2a × 2a
When side of a square is d × × 2a × 2a = 8xcube
Hence, volume will become 8 times
