Blocks are sold in boxes in bags or as single blocks. Each box has 10 bags in it. Each bag has 10 blocks in it. Tara needs 216 blocks,

She will need 3 Boxes with 94 blocks left over

So 1 box = 10 bags

1 bag = 10 blocks

so that means that 1 bag is 100 blocks.

So, if 1 bag is 100 blocks and 1 box is 10 bags, tara would need:

2 bags, since 2 bags are 100 blocks, plus

1 box, which is equivalent to 10 blocks, and

6 single blocks.
