Question

cubic units submit

Explanation:

Step1: Identify side - length of small cubes

Assume each small cube has a side - length of 1 unit. The large cube is composed of 5 small cubes along each edge.

Step2: Use volume formula for a cube

The volume formula of a cube is $V = s^3$, where $s$ is the side - length of the cube. Here, $s = 5$.
So, $V=5\times5\times5 = 125$.

Answer:

125
