How long are the cube's edges?

Video Solution

Solution Steps

00:00 Find the cube's edge
00:03 We'll use the formula for calculating cube volume (edge cubed)
00:07 We'll substitute appropriate values and solve for edge A
00:19 And this is the solution to the problem

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Identify the formula for the volume of a cube.
  • Step 2: Apply the formula with given values.
  • Step 3: Calculate the cube root to find the edge length.

Now, let's work through each step:

Step 1: The volume of a cube is given by the formula V=a3 V = a^3 , where a a is the edge length.

Step 2: We are given the volume V=1cm3 V = 1 \, \text{cm}^3 . Therefore, we have 1=a31 = a^3.

Step 3: To find a a , we take the cube root of both sides of the equation:

a=13=1cm a = \sqrt[3]{1} = 1 \, \text{cm} .

Thus, the edge length of the cube is 1cm\mathbf{1 \, \text{cm}}.

Answer

1 1 cm
