Plz me with 3 through 5 show ur work

The equation to find the volume of a pyramid is V= 
3.)  V=  → Multiply the top V= → Divide by 3 V=
4.)  V= → Multiply the top V= → Divide by 3 V=59.904 or V=59.9
5.)  Since you need to find h you put the V value in and keep the h value blank. 1,350= → 1,350= → Multiply 3 by both sides 3×1,350=×3 → 4,050=225×h → Divide 225 from both sides 4,050÷225=225×h÷225 → 18=h 

I hope that helps!
