1. If a pyramid of base B has its vertex at any point in a plane parallel to and distant h from the plane of the base, find its volume. 2. In the corner of a cellar is a pyramidal heap of coal. The base of the heap is an isosceles right triangle whose hypotenuse is 20 ft., and the altitude of the heap is 7 ft. If there are 35 cu. ft. in a ton of coal, how many tons are there in this heap? 3. A pottery manufacturer has an order to manufacture 5000 hanging vases each to hold ⅓ pt. of water when full. The vases are designed so as to fit into the corner of a room. The faces of each vase are triangular in shape and intersect to form a pointed bottom. The area of the polygon cut out of the plane of the base by the lateral faces is 3 sq. in. The height of the vase is 8 in. Compute the weight of pottery required if pottery weighs 130 lb. per cu. ft.

Island Bridge Problem: Suppose that you work for a construction company that is planning to build a bridge from the land to a point on an island in a lake (Figure $6-4 \mathrm{d}$ ). The only two places on the land to start the bridge are point $X$ and point $Y, 1000$ m apart. Point $X$ has better access to the lake but is farther from the island than point $Y .$ To help decide between $x$ and $y,$ you need the precise lengths of the two possible bridges. From $X$ you measure a $42^{\circ}$ angle to the point on the island, and from $Y$ you measure $58^{\circ}$a. How long would each bridge be? b. If constructing the bridge costs $\$ 370$ per meter, how much could be saved by constructing the shorter bridge? c. How much could be saved by constructing the shortest possible bridge (if that were okay)? (FIGURE CAN'T COPY)
