PA.GM.2. Calculate surface area and volume of three-dimensional figures.
PA.GM.2.1. Calculate the surface area of a rectangular prism using decomposition or nets. Use appropriate measurements such as cm^2.
PA.GM.2.2. Calculate the surface area of a cylinder, in terms of π and using approximations for π, using decomposition or nets. Use appropriate measurements such as cm^2.
PA.GM.2.3. Develop and use the formulas V = lwh and V = bh to determine the volume of rectangular prisms. Justify why base area (B) and height (h) are multiplied to find the volume of a rectangular prism. Use appropriate measurements such as cm^3.
PA.GM.2.4. Develop and use the formulas V = πr^2h and V = Bh to determine the volume of right cylinders, in terms of π and using approximations for π. Justify why base area (B) and height (h) are multiplied to find the volume of a right cylinder. Use appropriate measurements such as cm^3.
