Solution Steps

00:00 Find the cube's edge
00:04 We'll use the formula for calculating cube volume (edge to the power of 3)
00:09 We'll substitute the appropriate values and solve for edge A
00:26 We'll break down 27 into 3 cubed
00:33 We'll reduce what we can
00:37 And this is the solution to the question

Step-by-Step Solution

To solve for the side length of a cube with a volume of 27 cm³, we will apply the formula for the volume of a cube:

The formula for the volume of a cube is given by:

V=a3 V = a^3

where V V is the volume, and a a is the length of each side.

Given V=27 V = 27 cm³, we can solve for a a by taking the cube root of the volume:

a=V3 a = \sqrt[3]{V}

Substituting the given volume, we have:

a=273 a = \sqrt[3]{27}

Calculating the cube root, we find:

a=3 a = 3

Thus, the length of each side of the cube is 3 3 cm.
