Answer:
V = 396 cm³
Step-by-step explanation:
the volume (V) of the prism is calculated as
V = Ah ( A is the area of the triangular face and h the height of prism )
A =
bh ( b is base and h perpendicular height )
here b = 9, h = 8 , then
A =
× 9 × 8 = 4.5 × 8 = 36 cm² , so
V = 36 × 11 = 396 cm³
There you go. Sorry its blurry

Answer:
The length of the third piece of the ramp is;
D. 9.24 feet
Step-by-step explanation:
The given parameters are;
The height of the ramp = 8 feet
The angle between the piece that forms height and the base = 90°
The angle formed by the third piece connecting the height of the ramp to the furthest point and the 8 foot piece = 30°
Let 'y' represent the 8-foot piece forming the height, and let 'r' represent the third piece, by trigonometric ratio, we have;

Therefore, we get;


The length of the third piece, r ≈ 9.24 feet
