Solution to
UNITS OF VOLUME. In the metric system, the most commonly used

measurements of volume (capacity) are the liter, milliliter, cubic
centimeter, decaliter, and cubic meter.
Jill
A liter is equal to the volume of a cube measuring one decimeter (1/10 of
about 10 yards/9 m
a meter) on each side. The volume of a cube is found by multiplying the
(100 m = 110 yards. Jill ran
length of one side by itself three times (width x height x depth). Since a
110 yards
liter is a volume equal to 1 decimeter times 1 decimeter times 1
OR
decimeter, a liter can also be referred to as a cubic decimeter.
100 yards = 91 m. Jack
still needs to run 9 meters.
depth = 1
decimeter
= 1 liter (cubic decimeter)
height = 1
decimeter
width = 1 decimeter
Since a decimeter is 1/10 of a meter, how much larger is a cubic meter
than a cubic decimeter (l liter)?
(Hint: 1 meter = 10 decimeters)
depth = 10
decimeters
3
= 1 cubic meter (m )
height = 10
decimeters
width = 10 decimeters
