Gabriel is designing equally sized horse stalls that are each in the shape of a rectangular prism. each stall must be 9 feet high and have a volume of 1,080 cubic feet. the length of each stall should be 2 feet longer than its width. the volume of a rectangular prism is found using the formula v = l · w · h, where l is the length, w is the width, and h is the height. complete the equation that represents the volume of a stall in terms of its width of x feet. x2 + x = is it possible for the width of a stall to be 10 feet?
