When you mean estimate do you mean by rounding the first numbers?
The solution to the problem is as follows:
let
R = $619.15 periodic payment
i = 0.0676/12 the rate per month
n = 48 periods
S = the future value of an ordinary annuity
S = R[((1 + i)^n - 1)/i]
S = 619.15*[(1 + 0.0676/12)^48 - 1)/(0.0676/12)]
S = $34,015.99
I hope my answer has come to your help. God bless and have a nice day ahead!
I cant give you the answer without the picture but I can tell you how to solve it.
if all the sides are the same length just multiply one of the numbers by the sides, for example, a rubics cube is 9 cm on each side. 9*6=54, so the answer would be 54 cm
