cube :: Int -> Int -- cube takes in int, gives an int
cube x = x * x * x -- cuber x = x by x by x

edge, volume :: Int -- both are ints
edge = 3 -- edge = 3, set to 3

volume = cube edge -- volume = the cube of edge, cube of 3

surfaceArea :: Float -> Float -- surfaceArea takes in float, gives float
surfaceArea r = 4.0 * pi * r^2 -- radius = 4.0 by pi by radius raised to 2
