Step 1: Write out the formula for the volume V of a rectangular based pyramid with height h base length l and base width w:
[tex]V=l\cdot w\cdot h[/tex]
Step 2: Write out the given values and substitue them into the formula to find the volume:
From the image, we can see that:
[tex]l=12m,w=5m,h=9.5m[/tex]
Therefore,
[tex]V=(12)\cdot(5)\cdot(9.5)=570m^3[/tex]
Hence the volume of the pyramid is 570m³
