standard_description: Represent three-dimensional figures using nets made up of rectangles and triangles, and use the nets to find the surface area of these figures. Apply these techniques in the context of solving real-world and mathematical problems.
problem_activity: A tank that measures
$$1\frac{1}{2}$$
feet across,
$$2\frac{1}{3}$$
feet wide, and
$$1\frac{1}{2}$$
feet tall, is filled halfway with water, as shown below. To fill the tank to the very top with water, how many cubic feet of water need to be added?
