When we double each side of cube then why does its volume becomes 8 times. Please explain..
Let the original length of the side of a cube be x cm.
Volume of the cube = x3 cm3
If each side is double, the new length becomes 2x.
Volume of the cube with new length = (2x)3= 8x3 = 8(x3) = 8(Volume of original cube)
Hence when we double the side, the Volume becomes 8 times.
