Question

A plank measures 612.0inches. How many cm isthis?

Answer 1

Explanation

We know that a plank measures:

$x=612.0\text{ }in.$

The relation between inches and centimetres is given by:

$1\text{ }in=2.54\text{ }cm.$

Using this relation, we have:

$612.0\text{ }in=612.0\times(1\text{ }in)=612.0\times(2.54\text{ }cm)=(612.0\times2.54)\text{ }cm=1554.48\text{ }cm.$Answer

1554.48 cm
