Think of the doghouse as being a rectangular prism bottom and a triangular prism on top.
volume of prism: area of the base * height
Rectangular prism:
The base is a square 4.5 ft by 4.5 ft.
The height is 3.0 ft.
volume = 4.5 ft * 4.5 ft * 3.0 ft = 60.75 ft^3
Triangular prism:
The triangle facing the front is the base. The height is the depth, 4.5 ft.
For the triangle, the area is bh/2, where b = 4.5 ft, h = 1.5 ft
volume = bh/2 * height
volume = 4.5 ft * 1.5 ft / 2 * 4.5 ft = 15.1875 ft^3
Total volume = 60.75 ft^3 + 15.1875 ft^3
Total volume = 75.9375 ft^3
They each get one whole one and then half of one.
well that all depends on luck because you'll never land the exact same numbers again unless you get extremely lucky
Since the two lines are parallel the interior angles,
Angle 53 and angle 5, are supplementary angles therefore
53 + 5 = 180
5 = 127
