Question 905037
Have never seen a math question so vague and 'assuming' so to speak...
Given: Paint, used as mentioned, costs $1115 for 24m^2 of wall space
ASSUMING it is Walls in a ROOM we are to paint... l = 4m, w = 5m, h = 8m
4m x 5m x 8m ROOM ...would have 2(32m^2) + 2(40m^2) = 144m^2 in wall space.
Cost to paint? AND ASSUMING we go with 6 of each A & B, as mentioned 
(equal amounts of both) Cost =  6(1115) = $6690 
7*800 + 3*315 would work as well, cost $6545...but whatever...only said both
