Student name:

a) A deck needs to be constructed. (See sketch above.) The length of the deck is 3.170m. The foundation piles are 125 x 125 H4 radiata pine mounted in 325 x 325 concrete footings. Four are to be evenly spaced along its length. Calculate the spacings using the in and over method. (Distance A on the sketch).

b) You are preparing to dig out the footings. They are 325 x 325mm. Calculate the distance between the holes (Distance B on the sketch).

c) Seven joists need to be equally spaced along the bearer. Calculate the distance between centres for the joists to be positioned (Distance C on the sketch).

Complete the table below by converting the dimensions in the left column into millimetres and metres, millimetres and centimetres, or centimetres and metres.

Number	millimetres	centimetres	metres
Example 5cm	50	-	0.05
a.	75 mm
b.	25 cm
c.	1.3 m
d.	126 cm
e.	5 mm
f.	3800 mm
g.	1390mm

i.	.8 m
j.	.001 m
k.	109500 mm
l.	324 cm
m.	.4 cm
n.	5.600m

Select the most suitable measuring tool, measure it, and record the following dimensions in both millimetres and metres.

Millimetres	Metres
Height of a door
Thickness of a door
Length of a wall
Height of a desk
