If each brick weighs 2.81 kilograms, then 15 bricks will weigh how much in kilograms?

They will weigh 42.15 kilograms altogether.

You simply need to multiply 2.81 and 15 together to get 42.15. You would multiply 15 by 2.81 because each brick is 2.81 kilograms, the key word each gives you the hint to multiply. Thus, the bricks weigh 42.15 kilograms altogether.
