The function f(x) = 3x^2 models the packaging costs, in cents, for a box shaped like a rectangular prism. The side lengths are 4x ft, 5x ft, and 6x ft. What are reasonable domain and range values for this function, if the longest side length of the box can be no greater than 90 ft? WILL DO BRAINLIST

69 i think because is the only one square

The great thing about this problem is they give you everything you need to solve it easily. so the expression is: 12h+30w12h+30wand so everywhere you have an “h” you place 66. and everywhere you have a “w” you place 33. then the expression will look like this: 12(66)+30(33)12(66)+30(33)from here you multiply and then add. getting the following of: $785,862hope this
