THE ANSWERS ABOVE ARE WRONG.
==========================
Here's why...
First, picture a cube one inch on a side.
Each side is one square inch; Six square inches total of SURFACE AREA .
-------------------
SCENARIO #1
-------------------
A slice (either vertical or horizontal) will add TWO (2) more sides, each being an additional square inch, for a sum total of eight (8) square inches.
An increase of 2 sq. in. over the original six (6) sq. in. is an increase of 33 percent. So, for vertical or horizontal halving, the formula is, as follows:
[ORIGINAL SURFACE AREA times 1.33]
-------------------
SCENARIO #2
-------------------
But if you halve the cube on a diagonal, the resultant new surfaces will be oblong, measuring 1" by 1.414" (the Square Root of two) adding almost another square inch of surface area.
2 x ( 1 x 1.414) = 2.828 square inches
The total SURFACE AREA is now 8.828 (when halved on the DIAGONAL).
This is an INCREASE of 47.13333 percent.
Resultant formula:
[ORIGINAL SURFACE AREA times 1.4713]
-------------------
THEREFORE
-------------------
FINALLY, the answer to your question is somewhere between these two extremes, because your cut will be neither a perfect vertical cut, nor a perfect diagonal cut.
Total surface area of a cube = 6*area of cube face = 6*cube side*cube side
If many smaller cubes are combined to form a larger cube, then the surface area of the large cube is: 6 x (length of one side squared)
Zero. A cube does not have a curved surface area.
If a is the side,lateral surface area of cube=4a2
Total Surface Area of Cube is 6a2 . Here "a" is the "length of each side" of the cube.
Total surface area of a cube = 6*area of cube face = 6*cube side*cube side
If many smaller cubes are combined to form a larger cube, then the surface area of the large cube is: 6 x (length of one side squared)
The surface area of a 0.5cm cube is 1.5cm2
The surface area of a 1mm cube is 6mm2
Zero. A cube does not have a curved surface area.
Find the cube root of 125 which is 5. That tells you each of the lengths. Multiply the one side by another to get the area of one face. It is now 25. Multiply 25 by 6 to get the surface area of combined area of all the faces. This is now 150.
ok, so think about it. a cube has 6 sides. The surface area is the area of the surface of all 6 sides combined, so you divide the surface area by 6. This gives you the area of each square on each side. Then square root the answer because the area of a square is the side length squared. Now you have the edge length!
The volume of a cube that has a surface area of 343 is 432.2
Surface area also decreases
If a is the side,lateral surface area of cube=4a2
A cube has 6 sides, therefore a 1cm cube has a total surface area of 6 square centimeters.
The surface area of the cube is 150 square meters.
