A cereal box has a surface area of 272 square inches. the width is 2 inches and the height is 1 foot. the cereal box has a mass of 350 grams. what is the density of the cereal? Give an approximate answer accurate to three decimals. Be sure to include the units of measure

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

float.

denser than water sinks in water.

denser than mercury would sink in it
