What is the surface area of a 2cm x 2cm x 2cm cube?
A cube has six square faces. This cubes faces are 2 x 2 ie 4cm2 so overall surface area is 24 cm2.
What is the difference between a cube and a cube root?
The cube of a number is the value of the number multiplied by itself two times (or 1 multiplied by the number three times). A cube root is the inverse function so that if y is the cube of x the x is the cube root of y.
What is the square root of 192?
5.76899828 orFactor the 192:=8x24=8 x 8 x 3remember that cube root of 8 is 2, so you have:2 x 2 (cube root of 3) = 4 cube root of 3for the x^9, cube root is x^(9/3) = x^3final answer:4x^3(cube root 3)that's' it! ;)
What is the cube root of x?
x^1/3
How do you find the cube root of a negative number?
If the negative number is "-a", then you can say the cube root is "-(cube root of a)" Because if you cube a negative number, you get a negative number. So if you cube root a negative number, you get a negative number. Ex) cube root of -8 = -2 Because (-2)^3 = -8 But if you want to find the complex cube roots, you can make an equation: "x^3=-a" or "x^3+a=0" We know one of the roots is "-(cube root of a)" so you can factor the equation by (x+(cube root of a)) And then you use the quadratic formula for the quadratic equation you're left with. Ex) x^3=-8 or x^3+8=0 Since -2 is a root, factor it by (x+2) x^3+8=(x+2)(x^2-2x+4) Using the quadratic formula, you get "1+i√3" and "1-i√3" Therefore the three cube roots of -8 is <"-2", "1+i√3", "1-i√3">
How many rectangular prisms can you make with 18 unit cubes?
three.1 cube x 1 cube x 18 cubes1 cube x 2 cubes x 9 cubes1 cube x 3 cubes x 6 cubes
What does decompose a cube mean?
Let n > 1 for an n x n x n cube for the purpose of decomposing the n x n x n cube into unit cubes (1 x 1 x 1). For the above scenario we see that decomposing an n x n x n cube into unit cubes can be thought of dividing an n x n x n cube into unit cubes. When n = 2 we get 8 unit cubes after decomposing. When n = 3 we get 27 unit cubes after decomposing.If necessary to further your understanding I would suggest drawing a picture of a 2 x 2 x 2 cube then divide each of the six-faces by 2 both horizontally and vertically. Then draw a 3 x 3 x 3 cube and then divide each of its six-faces by 3 both horizontally and vertically. Then count the number of unit cubes for both drawings. Again, when n = 2 you should count 8 unit cubes and when n = 3 you should count 27 unit cubes.
A 10cm X 10cm X 10cm cube is cut into 1cm X 1cm X 1cm cubes some of these cubes are put together to form the largest possible cube looks solid on the outside but is hollow how many cubes are left?
134 cubes left.
HOW MANY CUBes if you have 3 rows of 3 cubes?
3 cubes x 3 rows = 9 cubes
How many cubes does 2 by 3 by 4 hold?
2 cubes wide x 3 cubes long x 4 cubes high. 2 X 3 X4 6 X 4 24 cubes
How many 1 cm cubes would it take to construct a cube that is 2 cm on edge?
2 x 2 x 2 = 8 cubes.
How many faces do 6 cubes have?
Each cube has 6 faces, so 6 cubes have 6 x 6= 36.
How many cubes are in a 27 cubed cube?
273 = 27 x 27 x 27 so...19683
How do you find the area of cubes together?
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)
If a cube is painter on all sides then cut up into 125 smaller cubes of equal size how many smaller cubes will have 1 painted face?
Each side will be 5 x 5 and the 3 x 3 in the centres will have 1 painted face so total will be 6 x 3 x 3 ie 54.
Are there 9x9x9 rubik's cubes?
there is a 9x9 rubiks cube but i dont think its possible for a cube to be #x#x# at all
What numbers are perfect cubes?
any number multiplied by itself three times is a cube number eg. 3 x 3 x 3 =27 5 x 5 x 5 =125 so 27 is a cube number, so is 125 you can work out if something is a cube number by cube rooting it there is a cube root button on most scientific calculators
