galina1969 [7]
So the actually surface area can be split up by dif parts....meaning
2 side is 2.7*3.2*2 = 17.28
2 side is 3.2*2.1*2 = 13.44
2 sides is 2.1*2.7*2=  11.34

then u add up the areas = 42.06ft^2

then u look for what is the clossest...and that is 42gt^2

What would be the value of $100 after 10 years if you earn 11 percent interest per year
uysha [10]
10 times 11% is 11 dollars, so 11 times 10 equals 110. Then 110 plus 100 equals 210. So you'd have $210 after ten years with 11 percent interest.
