Determine the volume of the figure.

The base of the pyramid is the triangle and we don't know it's height I need to
find it first. solve for h The numbers
are 5ft and 7ft on top and 6ft and 5ft on bottom. I have no idea how to do this
one can someone please help.

I do not understand your description.

if the base of the pyramid is a triangle, then
" the numbers are 5 ft and 7 ft on top and 6 ft and 5 ft on bottom" makes no sense to me.
