Answer:

720 in³

Step-by-step explanation:

The volume (V) of a right prism is calculated as

V = area of triangular end × length

area of Δ = $\frac{1}{2}$ bh

where b is the base and h the perpendicular height

here b = 8 and h = 15, thus

area of Δ = 0.5 × 8 × 15 = 4 × 15 = 60 in²

The length of the prism is 12 in, hence

V = 60 × 12 = 720 in³

AREA ADDITION AND SUBTRACTION ASSISTANCE?

Tom [10]

The shaded area is a segment. The area of a segment is

$A_{segment}=A_{sector}-A_{triangle}$ .

You know radius that is the side of isosceles triangle and measure of angle between two equal triangle sides, then

$A_{triangle} =\dfrac{1}{2} a\cdot a \sin \alpha=\dfrac{1}{2} 18.6\cdot 18.6 \cdot \sin 123^{\circ}=172.98\cdot \sin 123^{\circ}=145.07$ sq. m..

The area of sector is $A_{sector}=\dfrac{r^2\cdot \alpha}{2}= \dfrac{(18.6)^2\cdot 0.68\pi}{2}=117.63\pi=369.53$ sq. m..

Then $A_{segment}=369.53-145.07=224.46$ sq. m.

Answer: $A_{segment}=224.46$ sq. m.
