How do i calculate the volume of this pyramid?

V = 1/3 area of base * height

Area of  base = h [(b₁ +b₂)]/2

[(3 + 6) * 4] : 2 =

18 ft²

Volume =

18 * 3 =

54 ft³

answer: approximately 206 bones

i hope this u out a branlist and a would be greatly appreciated :

this is a geometric sequence with common ratio r

r = = = = 3

(a)

to obtain a term in the sequence multiply the previous term by 3

= 3 ← recursive rule

(b)

the n th term of a geometric sequence is

=

where is the first term and r the common ratio

= 6 × ← explicit rule
