Thus,
The cost of 1 pencil = $0.11
The cost of 100 pencils = $0.11 × 100
= $11
Therefore, we conclude that the cost of 100 pencils = $11

The amount of flour Mrs.Stewart needs for 5 cups of shortening
cups.
Step-by-step explanation:
Mrs.Stewart pie dough needs
cups of shortening for
cups of flour.
Now we assume that the shortening needed for
cups of flour is
cups.
Accordingly we can arrange the ratios.
So for one cup of shortening how many cups of flour is needed we have to use the unitary method:

Plugging the value of
as it is number of cups of shortening Mrs.Stewart have used.
And multiplying both sides with
.
Number of cups of flour needed when
cups of shortenings are used
.
So, 
The amount of floor Mrs.Stewart needed for
cups of shortening
cups of floor.
Answer:
<em>The volume inside the giant sugar cube is 27 cubic feet.</em>

It took 54 feet² of material to build the giant sugar cube. That means, the total surface area of the cube is 54 feet²
<u>Formula for surface area of a cube</u> is:
, where
is the length of each edge of the cube.
So, we will get.........

Now, <u>the volume of the cube will be</u>:
feet³
Thus, the volume inside the giant sugar cube is 27 cubic feet.
