the drains of a steam can be calculated by dividing the want over want & a graduated box can z a liquid's want & a slip can instinct a liquid's want ->  density can be measured using a graduated cylinder and a balance  density can be measured using a graduated cylinder and a balance & times can be used to predict whether a steam will sinking on land or raise under land -> a graduated cylinder and balance can be used to predict whether a liquid will float on water or sink on water
