Apyramid has a square base with side s. the height of the pyramid is that of its side. what is the expression for the volume of the pyramid? a. v = 2s2 b. v = 2s3 c. v = s2 d. v = s3 e. v = s3

we know that

Volume of a pyramid=(1/3)*[Area of the base]*height

area of the base> is a square base

length of the side=s

so

Area of the base=s²

height=s

substitute the values in the formula above

Volume of a pyramid=(1/3)*[s²]*s> volume=s³/3

therefore

the answer is

V=s³/3

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
