1. Find the value of 2-5
=

=

=

= 0.03125
2. A container has a volume of 0.216 m3.

Express this volume in cm3
1 litre = 1 dm

= 10 cm × 10 cm × 10 cm = 1000 cm

So 1l = 1000 cm3

0.216m = 216 litres

So 216 x 1000 = 216,000 cm3
3. A container has a volume of 0.216 m3.

Express this volume in litres
1 litre = 1 dm3

So 1 litre = m3

So if 1 litre is  of 1m then 1 m = 1000 l

So 0.216 m3 = 1000 × 0.216 litres

= 216 litres
4. A cubic container has sides each of length 0.800 m.

Calculate the volume of the container.

You should give your answer in m3 and to three decimal places.
= 0.8 x 0.8 x 0.8

= 0.512 m3
5. A floorboard has length 2.0 m and width 16 cm. What is its area?
2.0m x 16cm

= 2.0m x 0.16m

= 0.32m2

6. =

7.   = ?

2 significant figures

Use the least precise number of sf when multiplying
9. 12.123 / 4.15 should be answered with how many figures?
3 significant figures

Use the least precise sf quantity when dividing
10. 789.123 + 123.4 should be answred with how many figures
To 1 decimal place

Alwys use the least amount of decimal places when adding
11. 789.123 - 456.1 should be answered with how many figures?
To 1 decimal place

Always use the least amount of decimal places when subtracting
12. How would you show what Power is equal to in an equation?
Power = Energy/time
13. If 500 Joules are delivered in 20 seconds how much power is delivered?
P = E/t

Power = 500J / 20s

25 W (J s-1)
14. What is the density of an item with 100 kg mass & 20 m3 of volume?
Density = mass / volume

Density = 100 kg / 20 m3 = 5 kg m-3
