1.  Given: No information  Find: The Number of basketballs required to fill this classroom.

2. NamesEstimate 19,000 18,200 24,000 18,600

3. - Find dimensions of the room by number of tiles *(29/16) - Estimate number of basketballs to fill each tile *(4) - Estimate the number of basketballs to fill from the floor to the roof *(12) - Multiply these numbers to get the total number of basketballs needed

4. -The dimensions of the room are 29/16 - 4 basketballs are required to fill each tile - 10 basketballs to reach from the floor to the roof

5.  29X16=464 (number of tiles)  464X4=1856 (number of basketballs to fill the floor)  1856X12=22,272 (total number of basketballs to fill the room)
