Answer:
4
Step-by-step explanation:
You take 3/4 + 3/4 and add it. That equals 1.5, so you take 3/4+ 3/4 again and you get 1.5 . So, 1.5+1.5 is 3. So that's how you get your total of 4 boxes.

Answer:
It is 27.35 ft up the house
Step-by-step explanation:
The hypotenuse of the right triangle is 28 and the base is 6
We can use the pythagorean theorem to find how high it is
a^2 + b^2 = c^2
6^2 + b^2 = 28^2
36 + b^2 = 784
Subtract 36 from each side
36-36 + b^2 = 784-36
b^2 = 748
Take the square root of each side
b =sqrt(748)
b =27.34958866
It is 27.35 ft up the house
