To find the smaller side of a rectangular prism on each end you must multiply the width and height:
15*8=120
Then you must times this by 2 because we have 2 of those sides (one on each end):
120*2=240
Then find the rectangular shape's surface area by multiplying the length and the height:
10*8=80
You must then multiply this by 4 as there are four of those sides:
80*4=320
Then add the two answers together to find the total surface area:
320+240=560
Answer:
f(n+1) = f(n) - 5
Step-by-step explanation:
Just find some relationship between 2 numbers that are next to each other.
Answer:
C = 4 + 0.5d
Step-by-step explanation:
General equation: y = ax + b, with b is fixed term and a is rate per x.
Here,
C = y
fixed term b = 4
rate a = 0.5 per kilometer (d)
