Answer:
234 feet cubed
Step-by-step explanation:
6 1/2 * 8 = 52
52 * 4 1/2 = 234
I=PRT
r=rate in percent
t=time in years
p=principal
convert percent to decimal
assuming you means at 7%
percent means parst out of 100
7%=7/100=0.07
so ow we have
p=8000
r=0.07
t=5
i=8000 times 0.07 times 5
I=40000 0.07
I=2800
interest=$2800
