We have that
1) the lateral area----------------> L=P*h
P=(3+3+3) h=6
L=(3+3+3)*6=54 in²
the answer part 1) is the lateral area is 54 in²
2) the total area=------------- > S=P*h+2B
2B=2*[3*3/2] P*h=54
S=2*[3*3/2]+54=63 in²
the answer part 2) is the total area is 63 in²
An arithmetic sequence is a pattern of numbers that increase or decrease at a constant amount.
Step by step, we have:
1 • (-1)= -1
Then -1 • 1 = -1 and -1 • (-1)= 1 =》 1 - 1 = 0
