A container has a volume of 0.216 m
^{3}
.
Express this volume in cm
^{3}
1 litre = 1 dm
= 10 cm × 10 cm × 10 cm = 1000 cm
So 1l = 1000 cm
^{3}
0.216m
= 216 litres
So 216 x 1000 = 216,000 cm
^{3}
A container has a volume of 0.216 m
^{3}
.
Express this volume in litres
1 litre = 1 dm
^{3}
So 1 litre =
m
^{3}
So if 1 litre is
of 1m then 1 m = 1000 l
So 0.216 m
^{3}
= 1000 × 0.216 litres
= 216 litres
A cubic container has sides each of length 0.800 m.
Calculate the volume of the container.
You should give your answer in m
^{3}
and to three decimal places.
= 0.8 x 0.8 x 0.8
= 0.512 m

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

How would you show what Power is equal to in an equation?
Power = Energy/time
If 500 Joules are delivered in 20 seconds how much power is delivered?
P = E/t
Power = 500J / 20s
25 W (J s
^{-1}
)
