Measurement

  • Students analyze surface area and volume of right composite 3-D shapes.

    • Visualize and model the 2-D shapes that compose the surface of a composite 3-D shape, using 2-D models or a digital geometry environment.

    • Compare the surface area of a composite 3-D shape to the sum of the surface areas of the 3-D shapes from which it is composed.

    • Describe the effect of adding or removing one or more 3-D shapes on the surface area of a composite 3-D shape.

    • Calculate the surface area of composite 3-D shapes composed of prisms, pyramids, and cylinders.

    • Visualize and model a composite 3-D shape as a composition of multiple 3-D shapes, using 3-D models or a digital geometry environment.

    • Describe the effect of adding or removing one or more 3-D shapes on the volume of a composite 3-D shape.

    • Visualize the decomposition of a rectangular prism into rectangular pyramids, using 3-D models or a digital geometry environment.

    • Calculate the volume of composite 3-D shapes composed of prisms, pyramids, and cylinders, given the relevant formulas.

    • Solve problems involving surface area and volume of composite 3-D shapes.

    • Compare the surface areas of various rectangular prisms that have equal volumes, using cube structures or 2-D models.

    • Investigate the effect of decreasing the height and increasing the dimensions of the base on the volume of prisms, pyramids, and cylinders.

    • Solve problems involving surface area and volume in real-world situations.
