Question

the volume of this cube is 20,123.648 cubic millimeters. what is the value of u? u = millimeters

Explanation:

Step1: Recall cube - volume formula

The volume formula of a cube is $V = u^{3}$, where $V$ is the volume and $u$ is the side - length of the cube.

Step2: Solve for $u$

Given $V = 20123.648$, we have $u=\sqrt[3]{V}=\sqrt[3]{20123.648}$.
Calculating $\sqrt[3]{20123.648}=27.2$.

Answer:

$27.2$
