The surface area is the measure of the outside of the 3D shape. So, you have to find the areas of each of the sides and add them together. For surface area of a regular pyramid (which is what they are given in the book), find the area of the base. Then find the area of one of the triangle faces, multiply that by how many non base faces there are, then add that to the area of the base.
Volume of pyramids is just like for prisms, then divide by 3. So, (1) area of the base (2) times the height, then (3) divided by 3.
