Question

James is building a deck for a client and has several pieces of wood he wants to use. The sizes of the pieces of wood are:

 

 

1.5m 

2500mm

850mm

4.8m

 

What is the total length of wood in metres?

Answer 1

To convert mm to m... 

There are 1000mm per meter so divide number of mm by 1000 to convert to meters

 

1.5m

 

(2500mm)/(1000 mm/m) = 2.5m

 

(850mm)/(1000 mm/m) = 0.85m

 

4.8m

 

Add the number of meters:

1.5 + 2.5 + 0.85 + 4.8 = 9.65m
