write down the lower bound

Answer 1

`Lower\ Bound = 6.65cm`

Explanation:

Given

`Length = 6.7cm` to 2sf

Required

The lower bound

The lengths are approximately 6.7cm to 2sf are:

`Length = \{6.65 \to 6.74\}`

Such that:

`Length = \{Lower\ Bound \to Upper\ Bound\}`

So, by comparison:

`Lower\ Bound = 6.65cm`
