Lara is baking cookies using four baking trays. She places five rows of cookies on a baking tray where there are six cookies in one row. How many cookies is she baking?
Lara can bake 5 x 6 = <T>multiply(5, 6)=30 cookies in one tray.
So, Lara is baking a total of 30 x 4 = <T>multiply(30, 4)=120 cookies.
