Students will practice finding the surface area of cylinders, cones, spheres, triangular and rectangular prisms, and hemispheres with these 18 task cards. Students will have to use the Pythagorean Theorem to find the length of missing sides and should have a basic understanding of the parts of 3D shapes (such as slant height, B = area of the base, etc.) as well as be familiar with the formulas for these 3D figures.
I usually allow my students to use the End-of-Course exam reference sheet for geometry when completing these problems. That way they gain familiarity with the formulas and where they are located on their reference sheet. Formulas vary according to textbook, state standards, etc. For example, some of us may find the surface area of a rectangular prism by finding the sum of the products of the length and width, length and height, and width and height. Others may call the length “base” instead. In the answer key I have used the formula SA = Ph + 2B so that the students get used to using this formula and apply it to any prism where P is the perimeter of the base, h is the height of the prism, and B is the area of the base.
