Volume of a Cube Formula: V = a³
- <em>a</em> is a side length
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
<em>V</em> = 512 cm³
<u>Step 2: Find </u><em><u>a</u></em>
- Substitute in variables [Volume of a Cube Formula]: 512 cm³ = a³
- [Equality Property] Cube root both sides: 8 cm = a
- Rewrite: a = 8 cm
