18×3=54
3.99×2=7.98
54+7.98+45=106.98
106.98×.085=9.0933
106.98+9.0933=116.0733
rounded to 116.07
answer 116.07

f(22) then a is minutes =22 min and f(22)= percentage
64 cm^2. First find the area of the triangular faces by taking a quarter of the base and multiplying it by the height and then doubling it. After you've found the area of one of these faces multiply it by 4 to find the areas of all the triangular faces. Finally add the base square which is the base times base.
You just multiply the sides.
Firstly, it's easier if you convert both measurements to inches.
so you'd do 6 x 12 = 72 , 72 + 5 = 77 inches
and 4 x 12 = 48 , 48 + 3 = 51 inches.
Then you multiply the sides, so:
77 x 51 = 3927 inches
then you divide by 12 to get how many feet and inches it is
3927/12 = 327 feet and 4 inches
