Solution to

Jack ran a 100-yard race while Jill ran a 100-meter race.

Frame 4-19.

Who ran the longer race?

1 mile (actually, a little

less than a mile since a

By how much?

mile is about 1609 meters)

Solution to

Frame 4-20.

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
