Question

The combined volume of two identical cubes is 250 cubic centermeters. what is the measure of one cube's edge?

Answer 1

First, we know that the cubes are identical, therefore, they would have half the combined volume. 

Each cubes's individual volume is 250/2 = 125 cubic cm 

Since we know that this shape is a cube, we also know that all the dimensions of a cube are equal. 

v=s³ where v is the volume and s is the side length 

125 cubic cm=s³
∛125=s 
5 cm=s 

One of the cube's edge dimensions would be 5 cm.

Hope I helped :)
