Answer:
Volume of the rock=
Step-by-step explanation:
Volume of triangular pyramid = 
Where B is the area of base
H is the height of pyramid
Length if base of base triangle = 8.5 inches
Height of base = 4 inches
Area of base triangle = 
Height of pyramid = 12 inches
Volume of triangular pyramid = 
So, option D is true
Volume of the rock=
Step-by-step explanation:
x+y=12
3×+y=20
×=12-y
3 (12-y)+y=20
36-3y+y=20
36-4y=20
-4y=20-36
-4y= -16
y =16÷4
y=4
×+y=12
×+4=12
×=12-4
×=8
therefoer;y=4,x=8
Sir, there should be a polygon displayed, we can’t just get the answer out of the blue.
