Question 773354: 3. Bricks are delivered to a work site and stacked in rows and columns, forming a rectangular prism. The length of the prism is 1 foot greater than its width, and its height is 2 feet less than its width. Show how to find the dimensions of the prism formed by the bricks, given that its volume is 40 cubic feet.
Answer by CubeyThePenguin(3113)   (Show Source):
You can put this solution on YOUR website! w = width
w(w + 1)(w - 2) = 40
factors of 40: 1, 2, 4, 5, 8, 10, 20, 40
Pick 3 factors of 40 that multiply to 40: 2, 4, 5.
width = w = 4 ft
length = w + 1 = 5 ft
height = w - 2 = 2 ft
