Bri is doing her schoolwork in a room that is 10ft by 10ft. Since it’s the end of the year we’ve decided to fill this room with 3” diameter plastic balls to a depth of 3ft. Estimate the number of balls needed to fill her office space. To keep things consistent round the volumes of the plastic ball to the nearest thousandths.

A 100 pack of multi colored 3in plastic balls can be purchased at Walmart for 37.99. How much would it cost us to complete this prank.
