part a
the roberts family is planning to purchase an above-ground pool for their backyard. there are three different rectangular models that they are looking at.

model a: this pool has a length 18 feet and a width of 9 3/4 feet. the maximum depth of water is 4 1/2 feet.
model b: this pool has a length of 16 feet and a width of 10 feet. the maximum depth of water is 5 feet.
model c: this pool has a length of 15 feet and a width of 12 feet. the maximum depth of water is 4 1/2 feet.
one of the factors that the roberts family is considering is how much water is needed to completely fill up the pool.

question #1

of the three pools described, model __ needs the smallest amount of water to be completely filled.

a. model a
b. model b
c. model c

question #2
of the three pools described, model __ needs the largest amount of water to be completely filled.

a. model a
b. model b

model c: this pool has a length of 15 feet and a width of 12 feet. the maximum depth of water is 4 1/2 feet.

all three models require a liner that runs along the sides and bottom of the pool. another factor that the roberts family is considering is the size of this liner. hint: the pool is a rectangular prism. what is the formula for the surface area of this shape?

question #1
of the three pools described, model __ uses the smallest liner.

a. model a
b. model b
c. model c

question #2
of the three pools described, model __ uses the largest liner.

a. model a
b. model b
c. model c

part c (picture 1 or red roof)

a large mall is built in the shape of a square. at each corner of the mall stands a pillar which is topped by a pyramid-shaped section of red tin roof, as shown in the picture below.

the pyramid is a square pyramid, measuring 21.5 feet on each of its base edges. the height of each of the triangular lateral face is 13.4 feet. use this information to answer the following questions.

question #1
if you drew the net of this pyramid, the net would contain __ congruent triangular faces.

a. two different pairs of
b. three
c. four

question #2
how many square feet of red tin roof does each pillar contain? [type your answer as a number. do not round.]

square feet (for this one no choices just do it)

question #3
one of the roofers claims that the roof area of each pillar is the same as the area of a square with edges of 21.5 feet. the roofer is

a. correct
b. incorrect

part d (picture 2 or white roofed tent like house)

the following house is called an a-frame house because it looks like the letter a from the front.

suppose that all edges of this a-frame house measure 6.5 yards, and the height of the house is 5.6 yards. use this information to answer the following questions.

question #1
what is the area of the roof? [type your answer as a number. do not round.]

square yards

question #2
what is the outside surface area of this house? type your answer as a number. do not round.]

yards

question #3
this a-frame house is in the shape of a

a. triangular prism
b. square pyramid
c. triangular pyramid
d. rectangular prism
