Step-by-step explanation:

1. The formula is 18x3 since there is 3 equal area sides. The volume is 54 (probably)

2. The formula for the pyramid is 3x3x2/3. Which the volume is 6.

3. Same thing the volume is 60 and what i did to get that is 20x3

Hope this helps!

Answer:

Given : A=(1,2)≡(x  

1 ,y  

1

) and B=(3,−2)≡(x  

2

,y  

2

)

Let M=(x,y) be the midpoint of AB

x=(  

2

x  

1

+x  

2

 

) and  y=(  

2

y  

1

+y  

2

 

)

Then, x=  

2

1+3

and y=  

2

2−2

 

⟹x=2 and y=0

∴M=(2,0)

∴ Coordinates of the midpoint of AB is (2,0)
