Step-by-step explanation:
We have,
l =5ft
b=2ft
h=3ft

v = (l*b*h)
v = (5*2*3)ft
v = (30)ft
.•. v = 30ft
Rate of interest is 6 %
<em><u>Solution:</u></em>
Given in question that,
simple interest = $ 3240
number of years = 9 years
principal sum = $ 6000
To find: interest rate
<em><u>The simple interest is given as:</u></em>

Where, "p" is the principal
"r" is the rate of interest
"n" is the number of years
<em><u>Substituting the values in above formula,</u></em>

Thus rate of interest is 6 %
