15 meters/m is the volume of the cuboid
So we can use the formula 2lw +2wh+ 2lh, which is the surface area formula and we can set that to equal 20. 2lw +2wh+ 2lh=20
lw+wh+lh= 10
Let’s isolate L
Lw+Lh=10-wh
Let’s distribute L
L(w+h)=10-wh
L=(10-wh)/(w+h)
You can use this formula to plug in values for w and h and it will work as long as their products are less than 10
Hmm idk.... I need like more info for this please so I can help you thank you byeeeee
Answer:
$46,141.71
Step-by-step explanation:
This looks about right, based on weekly deposits for the duration. However, I cannot vouch for it entirely, as the number of weekly deposits in 15 years will actually be 782.
_____
Computing this by hand doing the initial balance separately from the weekly deposits, I get a total of $46,252.10 using 782 weekly deposits. For that purpose, I tried to figure an equivalent weekly interest rate given monthly compounding and the fact there are 52 5/28 weeks in a year on average.
I suspect the only way to get this to the cent would be to build a spreadsheet with payment dates and interest computation/payment dates. Some months, there would be 5 deposits between interest computations; some years there would be 53 deposits.
