Question 347656: Wendy, a landscaper, who just completed a rectangular flower garden measuring 25 feet by 15 feet, orders 3 cubic yards of pre-mixd cement, all of which is to be used to create a border of uniform width around the garden. if the border is to have a depth of 3 inches, how wide will the border be? Answer by nyc_function(2741) (Show Source):
You can put this solution on YOUR website! Let's start with how much cement there is: 3x3x3 yard = 9x9x9 feet 729 total
feet now convert that to inches 729 feet 12 inches to a foot = 8748 inches
divide that by 3 because its going to be uniformly 3 inches deep all the way
around, 2916. now its a 25x15 box so 2 sides are 25 and 2 are 15, or a total of
80 feet around. or 960 inches. 3.0375 inches....rounded to 3 inches so 3 inches
wide.
