A team in Mr. Ivy’s class made a model house with dimensions 15” wide by 18” long by 4” tall. What is the total volume of their house? Show your work.
Answer:
1,080 cu in.
Explanation:
With reference to the above given information,
A model house with dimensions 15” wide by 18” long by 4” tall
V = L x B x H
V = 15 x 18 x 4
V = 1,080 cu in.

Question 2.
Design a floor plan for the team that includes at least 4 rooms, and sketch it below. Label the dimensions of each room, and label your sketch with the scale factor you used.

Answer:

Explanation:
With reference to the above given information,
A model house with dimensions 15” wide by 18” long by 4” tall
A floor plan for the team that includes at least 4 rooms are,
Room 1: 6″ × 12″ = 72 sq in.
Room 2: 6″ × 6″ = 36 sq in.
Room 3: 9″ × 12″ = 108 sq in.
Room 4: 6″ × 9″ = 54 sq in.

Question 3.
If the dimensions of the entire floor of the model house are 15″ × 18″, what is the area of the floor in each room? Show your work.
Answer:
270 sq in.
Explanation:
With reference to the above given information,
the model house dimensions are 15″ × 18″,
Area = length × width
Area =  15″ × 18″
Area = 270 sq in.

Question 4.
Find the volume of each room in the house. Then show that the volume of all the rooms added together equals the total volume of the house. Remember that the model house is 4” tall. Show your work.
Answer:
1,080 in³
Explanation:
With reference to the above given information,
the model house dimensions are 15″ × 18″ × 4″
volume = l × b × h
V = 15″ × 18″ × 4″
V = 1,080 in³

Question 5.
CHALLENGE What is the volume of each room in the actual house if the scale is 25:1? Show your work.
Answer:
the actual house if the scale is 25:1
V = 27000 in³
V = 2,250 sq ft
Explanation:
With reference to the above given information,
the volume of each room in the actual house if the scale is 25:1
the model house dimensions are 15″ × 18″ × 4″
volume = 15″ × 18″ × 4″
V = 1,080 in³
V = 1,080 x 25
the actual house if the scale is 25:1
V = 27000 in³
V = 2,250 sq ft.
