The volume is ___ cubic cm.

Step-by-step explanation:

This looked very difficult UNTIL I looked at the pyramid as ONE HALF of a larger pyramid!    Image a mirror image of the pyramid creating a pyramid that is 12 cm of the front and back side and 6 cm on the left and right edge.

IT IS NO LONGER A SQUARE PYAMID so you need the volume for a rectanglar pyramid

The volume of a square pyramide is    

      V = side² × (height / 3)

The volume of a rectangular pyramide is    

      V = base area × (height / 3)      

         =  length × width × (height / 3)

         =  12 × 6 × 10 / 3    cm³        BUT REMEMBER we want only HALF of the

         = [12 × 3 × 10] divide by 2 cm³          Rectangular pyamid

Volume of the image shown in the diagram is

          = 360 / 2  cm³

          = 180 cm³    <  Final Answer

120

Step-by-step explanation:

I calculated it on Goggle

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right
