Answer:
<h2>V = 27m³</h2>
Step-by-step explanation:
We know: All faces of a cube are squares.
The formula of an area of a square with a side <em>s</em>:
<em>A = s²</em>
We have <em>A = 9m²</em>
Substitute:
<em>s² = 9 → s = √9 = 3 m</em>.
The formula of a volume of a cube with an edge <em>s</em>:
<em>V = s³</em>
Substitute:
<em>V = 3³ = 27 m³</em>
