Question 1
What is the conditioned floor area (area within the solid blue lines) of the plan below?
Sorry that's incorrect.
Hint 1: From top to bottom and left to right, the areas created by the dashed lines are:
Hint 1: From top to bottom and left to right, the areas created by the dashed lines are:
- 18.0’x8.0’
- 46'6"x12.0’
- 28'6"x12.0’
- 9.0’x4.0’
- 12'6"x8.0'
Still not right.
Hint 2: Add these individual areas together to get the total area.
Hint 2: Add these individual areas together to get the total area.
That's correct.
Question 2
What is the perimeter of the conditioned space of the plan below?
Sorry that's incorrect.
Hint 1: Add each length of the conditioned space’s walls, including the 16.0’ and 18.0’ walls adjacent to the garage.
Hint 1: Add each length of the conditioned space’s walls, including the 16.0’ and 18.0’ walls adjacent to the garage.
Still not right.
Hint 2: Clockwise starting from the top left corner, add 18.0’ + 8.0’ + 28.5’ + 32.0’ + 12.5’ + 8.0’ + 7.0’ + 4.0’ + 9.0’ + 16.0’ + 18.0’ + 20.0’.
Hint 2: Clockwise starting from the top left corner, add 18.0’ + 8.0’ + 28.5’ + 32.0’ + 12.5’ + 8.0’ + 7.0’ + 4.0’ + 9.0’ + 16.0’ + 18.0’ + 20.0’.
That's correct.
Question 3
As shown in the simple house section view below, a house has three rectangular rooms with different flat ceiling heights, including:- A main living and master bedroom section that is 45.0’ long by 32.0’ wide with a 10.0’ ceiling height
- An entry section that is 12.0’ long by 11.0’ wide with a 11.33’ ceiling height
- A bedroom section that is 38.0’ long by 12.0’ wide with a 9.0’ ceiling height
Sorry that's incorrect.
Hint 1: First calculate each room’s volume-- (45.0’x32.0’x10.0’); (12.0’x11.0’x11.33’); and (38.0’x12.0’x9.0’)
Hint 1: First calculate each room’s volume-- (45.0’x32.0’x10.0’); (12.0’x11.0’x11.33’); and (38.0’x12.0’x9.0’)
Still not right.
Hint 2: Add these three room volumes together (14,400 cu. ft. + 1,496 cu. ft. + 4,104 cu. ft.)
Hint 2: Add these three room volumes together (14,400 cu. ft. + 1,496 cu. ft. + 4,104 cu. ft.)
That's correct.
Question 4
A rectangular family room with a sloped ceiling has the dimensions shown below. What is the volume of this room?(Hint: calculate the average height of the ceiling.)
Sorry that's incorrect.
Hint 1: The room’s average ceiling height can be calculated by adding the left side wall height (9.0’) and right side wall height (12.0’) and dividing by 2.
Hint 1: The room’s average ceiling height can be calculated by adding the left side wall height (9.0’) and right side wall height (12.0’) and dividing by 2.
Still not right.
Hint 2: Calculate the room’s volume by multiplying its average ceiling height by its length and width.
Hint 2: Calculate the room’s volume by multiplying its average ceiling height by its length and width.
That's correct.
Question 5
For the ceiling illustration below, use the Pythagorean theorem equation to calculate the length of sloped ceiling Side C if Side A is 15.0’ long and Side B (knee wall) is 4.0’ tall.
Sorry that's incorrect.
Hint: The length of the sloped ceiling Side
; square root calculators are available online.
Hint: The length of the sloped ceiling Side
; square root calculators are available online.
That's correct.
Question 6
What is the total area of the ceiling in Question 5 (including flat, sloped and knee wall sections) if the house is a 40.0’ long by 30.0’ deep rectangle.Sorry that's incorrect.
Hint: there are three ceiling areas-- flat is 25.0’x30.0’, knee wall is 4.0’x30.0’, and sloped is 15.5’x30.0
Hint: there are three ceiling areas-- flat is 25.0’x30.0’, knee wall is 4.0’x30.0’, and sloped is 15.5’x30.0
That's correct.
