A box of chalk weighs 11.5kg. When the box of chalk is a half full of chalk, it weighs 6.5kg. Calculate the weight of chalk only

Answer 1

To find the weight of chalk only, you need to subtract the weight of the box from the weight of the box with chalk.

Weight of chalk = Weight of box with chalk - Weight of empty box

Weight of chalk = 6.5kg - 11.5kg

Weight of chalk = -5kg

Since the weight cannot be negative, it seems there is an error in the given information. Please check again.
