Physics homework

Full work and explanations, in complete sentences, required for all items. 1) Two objects have equal numbers of equal mass particles, but object A has a larger surface area than B. What, if anything, can we say about the volumes of the objects? 2) Two objects have equal numbers of equal mass particles, but object A has a larger volume than B. What, if anything, can we say about the surface areas of the objects? 3) Two objects have equal numbers of particles, but the particles of object A have a larger mass than those in object B. If object B has a smaller surface area, can it have a larger density than object A? Explain. 4) Object A has larger number of smaller mass particles than object B. Object A has a smaller surface area than object B. What, if anything, can we say about how tightly packed the particles are in these two objects? Explain
