 Math Central Quandaries & Queries
 Question from Bruce, a parent: Hello there, I need two cubic yards of concrete for a playgound I am installing for my kids. That much i have figured out. I am stumped over the number of 25kg bags of pre-mixed concrete i will need to accomplish my goal. Your help would be greatly appreciated. Thanks Bruce

Hi Bruce,

Do the bags tell you how many cubic feet of concrete they will produce? I have no idea. There are $3 \times 3 \times 3 = 27$ cubic feet in a cubic yard so you need $54$ cubic feet of concrete.
