Answer:
Question 2) 96 Question 3) 246
Step-by-step explanation:
Question 2:
The area of one side of the square is 4x4 which is 16 then you know a cube has 6 sides so 16x6 which is 96.
Question 3:
Well we know the two sides are squares with 3x3 which is 9 and then there are two so 9x2 which is 18
Then the front side with dimensions of 19x3 which is 57 and we know there are 4 sides so we do 57x4 which leads us to 228
Then we add 18 and 228 to find 246
Answer:
The door has a width of 6.26 feet, with a height of 12.52 feet.
Step-by-step explanation:
You can solve this by taking two pieces of information we're given:
1) the diagonal size of the doorway is 14 feet
2) the height of the doorway twice its width
First lets describe the width and height using the diagonal length. We can do that with the Pythagorean theorem:
w² + h² = 14²
Now we can use the relationship between the width and height to eliminate one variable:
w² + (2w)² = 14²
w² + 4w² = 14²
5w² = 196
w² = 39.2
w ≈ 6.26
So the door has a width of 6.26 feet, with a height of double that, 12.52 feet.
