The volume of a cube is 27cm3. Find the length of edge
27 = s^3
To find the length of an edge of a cube when the volume is known, you need to use the formula for the volume of a cube. The formula is:
Volume = length^3
In this case, you are given that the volume is 27 cm^3. So, plug in the given value into the formula:
27 = length^3
To find the length, you need to find the cube root of 27. The cube root of a number can be calculated using a scientific calculator or by using the concept of prime factorization.
Prime factorization of 27 can be expressed as 3 * 3 * 3.
Taking the cube root of 27 gives:
∛27 = ∛(3 * 3 * 3) = 3
So, the length of each edge of the cube is 3 cm.
