Colby wants to set square tiles on the top of a wooden box. the top of the box is a rectangle 7 1/2 inches long and 5 1/2 inches wide.

How many 1/4 inch tiles would Colby need to cover the top box?

7 1/2 long and 5 1/2 wide is 15/2 long and 11/2 wide

so there would be 15 half inch tiles across and 11 half inch tiles up

(15)(11) = 165 half inch tiles

Colby would need twice as many 1/4 inch tiles across and up to cover the box

(30)(22) = 660 quarter inch tiles
