The perimeter of the base of a regular quadrilateral prism is 60 cm, the area of one of the lateral faces is 105 cm2. Find:
Ostrovityanka [42]
The surface area is 870 cm².

Since the base is a regular quadrilateral, each side is the same; dividing the perimeter by 4 will give us the side length:

60/4 = 15

To find the area, we square the side length:
15² = 225

There are two bases, so the area of these is 2(225) = 450

There are 4 lateral faces, so the lateral area is 4(105) = 420

Together, this gives us a total surface area of 870.

 WILL GIVE BRAINLIEST ANSWER PLEASE HELP In a theater there are 12 seats on the first row and 16 seats in the second row. the nu
faltersainse [42]

(a) a_{n} = 4n + 8

(b) row 13 has 60 seats

(a)

the sequence of seats is an arithmetic sequence whose n th term is

a_{n} = a_{1} + (n - 1 )d

where a_{1} is the first term and d the common difference

here the sequence is 12, 16, ....

with a_{1} = 12 and d = 16 - 12 = 4, thus

a_{n} = 12 + 4( n - 1 ) = 12 + 4n - 4 = 4n + 8

(b)

calculate the number of rows n when 60 seats

solve 4n + 8 = 60 ( subtract 8 from both sides )

4n = 52 ( divide both sides by 4 )

n = 13 ← number of rows
