# Cube containers

Two containers shaped of cube with edges of 0.7 m and 0.9 m replace a single cube so that it has the same volume as the original two together. What is the length of the edges of the new cube?

Result

a =  1.023 m

#### Solution:

$a=\sqrt[3]{ 0.7^{ 3 }+0.9^{ 3 }}=1.023 \ \text{m}$
