Question

The diagonal of a cube is 28 cm. Identify the length of an edge. Round to the nearest tenth, if necessary. HELP PLEASE!!

Answer 1

`16.2\ cm`

Explanation:

we know that

The diagonal of a cube is equal to

`D=b√(3)`

where

b is the length of an edge of the cube

we have

`D=28\ cm`

substitute

`28=b√(3)`

`b=28/√(3)=16.2\ cm`
