If the length of each edge of a cube is tripled, what will be the change in its volume?

Solution:

The volume of a cube(V) = s³

Where ‘s’ is the length of edge

If the edge of the cube is tripled the volume will become:

V = (3s)³

V = 27s³

The new volume is 27 times the original volume.

✦ Try This: If the length of each edge of a cube is doubled, what will be the change in its volume?

The volume of a cube(V) = s³

Where ‘s’ is the length of edge

If the edge of cube is double the volume will become:

V = (2s)³

V = 8s³

The volume of the cube will increase to 8 times the original volume.
