Answer:
volume from geometri always:
base area × h
if have peak point always:
1/3 × base area × h
the base of the pyramid in the figure is rectangle. then base from rect. is:
l × w
= 9 × 7
= 63
let get into formula: (use the second formula because pyramid has a peak point)
=1/3 × ba × h
=1/3 × 63 × 7
=21 × 7
=147 yd³
