1. The problem is to understand the number 27 and its properties. 2. 27 is a natural number that comes after 26 and before 28. 3. It is a perfect cube because it can be expressed as $3^3 = 3 \times 3 \times 3 = 27$. 4. This means 27 is the volume of a cube with side length 3 units. 5. In prime factorization, 27 is $3^3$, meaning it is composed of the prime number 3 multiplied by itself three times. 6. 27 is an odd number and not a prime number since it has divisors other than 1 and itself (1, 3, 9, 27). 7. Understanding 27 as a cube helps in algebra and geometry problems involving volumes and powers. Final answer: 27 is $3^3$, a perfect cube and an odd composite number.
