It will increase by a factor of 4; in other words, it will be 4 times greater.
Given that all sides of a cube are of equal dimension, I will call this variable dimension x. The surface area is, therefore, x2. If the side of the cube is doubled (2x), then the surface area would be (2x)(2x) = (2x)2 = 4x2.
So:
x --> 2x (the side length is doubled)
x2 --> 4x2 (the surface area is quadrupled)

What happens to the surface area and volume of a cell as it becomes larger?
They both increase with increasing cell radius (if we model a cell as a sphere). However, the rate of increase of the surface area is in general slower (dA/dr = 8πr) compared to the rate of increase of the volume (dV/dr = 4πr2). This would mean that with increasing cell size, the surface area to volume ratio is becoming smaller and smaller, giving a cell less surface area for the transport of nutrients for a given unit volume.
What is the relationship between surface area and rate of reaction?
The increase in surface area of reactants increases the contact between reacting molecules, atoms or ions so the rate of reaction becomes increased.
Why fins are provided on heat transferring surfaces?
Using fins increases the surface area of the cover plate and more is the surface area meaning more place for heat dissipation or heat exchange. In simple words it multiplies the cooling effect.
What can change the surface area to volume ratio?
Yes. There are ways to do that, but it depends on what you wish to change the surface area of. Changing the surface area of something like, say, a shotput is difficult, but changing the surface area of a balloon can be accomplished by merely blowing it up (more) or deflating it.
Why does crushing help a solid solute dissolve?
The rate of dissolution of a solid is dependent on the surface area reaction. By crushing the cube, the surface area is greatly increased, thus increasing the rate of dissolution.
What is surface area and how you can decrease or increase surface area?
You can increase surface area by spreading the object
What does it mean to increase the surface area of a solid?
increase the surface area of a solid means to increase the area of solid
When you crush a solid do you increase or decrease surface area?
You increase the surface area
Why is the inner mitochondrial membrne folded?
The mitochondrial membrane's cristae are similar in size to villa lining the intestine and are there for much of the same purpose, to increase surface area for absorption.
What does a cell need to do to increase its surface area?
To increase surface area, a cell will have to grow. But most cells have restraints that interfere with too much growth. Only cancer cells don't bide by the rules.
An adaptation to increase the surface area of a part of a cell that is involved in cellular respiration?
Rugae is the folding of the surface of an organelle to increase the surface area of a volume.
How did god greatly increase the surface area of the intestines?
He invented the villi. Villi are extremely tiny nodes that pop out of the intestines walls, making the surface area greater. They also have other little nodes attached to the villi which increase the surface area further. Why does the intestine need so much surface area? Because the more surface area there is, the more nutrients can be absorbed at one time into the blood stream.
If you increase the surface area of water then the evaporation rate will do what?
Increase also.
How do circular folds increase the surface area for digestion and absorption in the intestine?
Folds increase the surface area to volume ratio.Imagine a circle with folds all around the edge and another circle the same size with a flat edge. Both circles have the same volume, but the one with the folds has a much larger surface area.
Convolutions of the brain provide increased what?
The convolutions increase the surface are of the cerebrum.
Why does the mitochondria have folds?
Generating ATP is efficient whe surface area is high.Inner folds increase the surface area.
What is the purpose of folds and wrinkles of membranes?
to provide a greater surface area in the organelle (increase surface area)
