Answer:
Step-by-step explanation:
It is useful to remember the ratios between the side lengths of these special triangles.
30°-60°-90° ⇒ 1 : √3 : 2
45°-45°-90° ⇒ 1 : 1 : √2
__
h is the shortest side, and the given length is the intermediate side. This means ...
h/1 = 2/√3
h = 2/√3 = (2/3)√3 . . . . . . simplify, rationalize the denominator
__
b is the longest side, and the given length is the short side. This means ...
b/√2 = 3/1
b = 3√2 . . . . . multiply by √2
Answer:
846 m³
Step-by-step explanation:
The solid consists of a rectangular prism and a rectangular pyramid.
V = LWH + (1/3)LWh
V = 9 m * 6 m * 12 m + 1/3 * 9 m * 6 m * 11 m
V = 648 m³ + 198 m³
V = 846 m³
