Any number n with an exponent of 3 is written as n³. You pronounce it as "n cubed," or "nto the third power." To get the cube of a number multiply it by itself 3 times. Therefore the cube formula is n³ = n × n × n.
A perfect cube results when you cube an integer, or a whole number without decimals or fractions. For example, 3 cubed is written as 3³ and 3³ = 3 × 3 × 3 = 27. Since 3 is an integer, 27 is a perfect cube. Imagine a block of smaller cubes 3 high, 3 wide, and 3 deep resembling a Rubik's Cube puzzle. Basically it's 3 sets of 9 blocks arranged in a 3 ...
When you cube a negative number the result will always be a negative number. But it is important to understand how using parentheses affects the intepretation of the operation. Putting a negative sign before the number or outside of parentheses means "take the negative of the number, cubed" as in 1. -2³ means -(2 × 2 × 2) = -8 2. -(2)³ means -(2 × ...
A “number cubed” refers to the multiplication of the number with itself and again by itself, i.e., multiplication of the same number two times. In other words, we can find the cube of a number by multiplying the square of a number by the number itself.
- Yes, 343 is a cube number as it can be written as $343^3 = 7 \times 7 \times 7$.
- Yes, cubes of negative numbers are negative cube numbers. For example, $(−2)^3 = −8,\; (−3)^3 = −27,\; (−4)^3 = −64$, etc.
- Cube of $−5 = (−5)^3 = −125$.
- Perfect cube numbers between 1 and 500 are 1, 8, 27, 64, 125, 216, and 343. Hence, there are a total of eight perfect cube numbers between 1 and 500.
- Perfect cube numbers between 1 and 100 are 1, 8, 27, and 64, out of which only 1 and 64 are perfect squares.
