You are to construct an open rectangular box with a square base and a volume of 48 ft^3. if material for the bottom costs $6/ft^2 and the material for the sides costs $4/ft^2 what dimensions will result in the least expensive box. what are its dimensions?

Angle xyz is formed by segments xy and yz on the coordinate grid below: a coordinate plane is shown. angle xyz has endpoints at 3 comma negative 1 and 6 negative 2 and 3 comma negative 3 and measures 36.87 degrees. angle xyz is rotated 270 degrees counterclockwise about the origin to form angle x′y′z′. which statement shows the measure of angle x′y′z′?
