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.
Surface Area: The area of one side is s2, where s is the length of 1 edge of the cube. So the total area is 6s2. If the edge length is half, the new cube area is 6(s/2)2 = 6s2/4, So the new surface area is the original area divided by 4.The volume of the cube is s3. If the edge length is half, the new cube volume is (s/2)3. = (s)3/8. So the new volume is the original volume divided by 8.
half of a cube is called a tetrahedron
Total surface area = (piradius2)+(piradius*slant length)
Oh, dude, you just need to find the radius first, which is half of the diameter, so that's 9 cm. Then you use the formula for the surface area of a sphere, which is 4πr^2. Plug in 9 for r, square it, multiply by 4, and then multiply by π. That gives you a surface area of 1017π square cm, or about 3190 square cm. Easy peasy!
Oh, dude, you're hitting me with some math here. So, the formula for the surface area of a sphere is 4πr², where r is the radius. Since the diameter is 18 cm, the radius is half of that, which is 9 cm. Plug that into the formula, and you get a surface area of 1017π cm². But like, who's really gonna measure that in real life, am I right?
No, it is not. It is half of it.
because
Yes it is possible.
The surface area of a cube with an edge length of 5.5 yards is: 181.5 square yards.
surface area of each piece would be 100 sq.inch
Surface Area: The area of one side is s2, where s is the length of 1 edge of the cube. So the total area is 6s2. If the edge length is half, the new cube area is 6(s/2)2 = 6s2/4, So the new surface area is the original area divided by 4.The volume of the cube is s3. If the edge length is half, the new cube volume is (s/2)3. = (s)3/8. So the new volume is the original volume divided by 8.
It is 6*8.5^2 = 433.5 square inches.
Yes it will be less because if you take a net of a cube and find the surface area it would be for example 30cm2 and if it was cut in half it would be 15cm squared so its smallerCORRECT ANSWER:Neither. It will be more in area because although you have made two halves of a cube, you have added a new exposed side on each of the halves, thus making 2 sides the same size as the cube. It will lessen by half the area on 4 of the sides which are bisected. So you get the same area that you started with. The above formula is close, but did not account for the other half.

The surface area of a semicircle has the round surface which is half a sphere and also has the flat surface which is a circle.
The surface-area-to-volume ratio also called the surface-to-volume ratio and variously denoted sa/volor SA:V, is the amount of surface area per unit volume of an object or collection of objects. The surface-area-to-volume ratio is measured in units of inverse distance. A cube with sides of length a will have a surface area of 6a2 and a volume of a3. The surface to volume ratio for a cube is thus shown as .For a given shape, SA:V is inversely proportional to size. A cube 2 m on a side has a ratio of 3 m−1, half that of a cube 1 m on a side. On the converse, preserving SA:V as size increases requires changing to a less compact shape.
If the length of an edge is x, the volume is x3 To find the rate of change of the volume with respect to x, differentiate: d(x3)/dx = 3x2 The area of one face is x2 There are six faces so the total surface area is 6x2 Therefore the rate of change of volume, 3x2 , is half of 6x2 , the surface area.
When you cut an orange in half, the surface area increases while the volume stays the same. This results in an increase in the surface area to volume ratio because the surface area expands while the volume remains constant.
