Well for volume you just do lxwxh ( length times width times height) so that would be 3 x 8 x 2 = 48 so the volume is 48 for surface area it’s a lot more complicated so if you don’t understand i get it so for surface area you open up the box so if you were to look at it from the top then you would only see the one rectangle if you were to look at it for the sides the you would see another rectangle but the size of the rectangle is different on each side so if you look at the top you would see a rectangle that is 8 by 3 so you would do 8x3=24 and then multiply it by 2 because there’s another one that looks exactly like it then you would have to look at it from the side all you see if one rectangle that is 8 by 2 so you do 8x2=16 and multiply it by 2 then look at it from the front you see a rectangle that is it 3 by 2 so you would do 3x2=6 then multiply it by 2 cuz of the rectangle on the back then at last you would have 48+32+6=86 so the surface area is 86
<span>If the interest is comounded every 2 months then you will
apply the interest 6 times in a year. So the value of n that you will plug into
your equation is 6 because there 12 months a year then it wll be compounded
every 2 months</span>
