The volume of a box is 0.001 cubic units. If the box is a cube, what is the length of one of its edges?

Respuesta :

Answer: 0.1 units

===============================================

Work Shown:

0.001 = 1/1000

Apply the cube root to both parts of 1/1000 to get

[tex]\sqrt[3]{1} = 1\\\\\sqrt[3]{1000} = 10[/tex]

So this means that, [tex]\left(\frac{1}{10}\right)^3 = \frac{1}{10}*\frac{1}{10}*\frac{1}{10} = \frac{1}{1000} = 0.001[/tex]

Having a side length of 1/10 = 0.1 unit leads to a volume of 0.001 cubic units.

-------------

A shortcut alternative is to use your calculator to get

[tex](0.001)^{1/3} = 0.1[/tex]

The exponent of 1/3 is the same as a cube root.
