As an example. Take a block of butter. 'Butter' because it weill cut easily.
As sold, it will have six faces of say 2 x 3 x 6 =
So surface area is
2[(2 x 3) + (3x6) +( 2 x 6)] = 2[6 + 18 + 12] = 72 unuts^2
Now cut the block into two equal sized blocks . Each block will have 2 x 3 x 3 dimensions.
2[(2 x 3) + (3x3) +( 2 x 3 )] = 2[6 + 9 + 9] = 48 unuts^2
However there are two blocks so 48 ubits^2 + 48 units^2 = 96 units^2
Hence
One block : 2 blocks :: 72 units^32 : 96 units^2
So surface area has increased.

When you crush a solid do you increase or decrease surface area?
You increase the surface area
Does crushing a solute increase or decrease its total surface area?
Increase...by alot.
Do cells divide to have a smaller surface area?
No. In fact, if they retain their combined volume, their surface area would increase.
Why do smaller cells have a greater surface area to volume ratio?
If the cells are spherical, the surface area increases as the square of the radius while the volume increases as the cube of the radius. Therefore, as the cells become larger, their volumes increase much more rapidly than their surface areas. Conversely, as the cells become smaller, their volumes decrease much more rapidly that their areas and so the surface area to volume increase. With non-spherical cells the calculations are much more complex, but the general pattern still applies.
What is the tendency of liquids to decreases their surface area to the smallest size possible?
The surface area of the liquid can decrease when there is increase in the temperature of the day,what is called evaporation is been taking place in the surface of the liquid,wchich decreases the liquid area.
