What happens to the volume of a cube if the length of an edge is doubled?
Doubled: Volume increased 8 times
Tripled: Volume increased 27 times
Quadrupled: Volume increased 64 times
Pretty simple... if you're doubling the lengths, you're increasing them by 2 times. Take 2 and raise it to the 3rd power. If you're tripling the lengths, you're increasing them 3 times over. Take 3 and raise it to the 3rd power. And so on.
Doubled = 2^3 = 8
Tripled = 3^3 = 27
Quadrupled = 4^3 = 64
Does that make sense?
Answer:
The new volume of the larger cube becomes eight times of the smaller cube.
Step-by-step explanation:
Let the edge of the cube be x.
Volume of cube = V = \(x^3\)..[1]
If we double the edge of the cube, then edge of the cube becomes = 2x
The volume of cube whose edges are doubled = V'
\(V'=(2x)^3=8x^3\),..[2]
Dividing [1] and [2]:
\(\frac{V}{V'}=\frac{x^3}{8x^3}\)
\(V'=8\times V\)
The new volume of the larger cube becomes eight times of the smaller cube.
