What skill is Mrs. Nadir trying to teach her students regarding surface area calculations?

Mrs. Nadir is focused on teaching her students how to determine area using formulas, which is essential for calculating the surface area of three-dimensional shapes. This skill involves understanding the specific formulas associated with different geometric figures, such as cubes, rectangular prisms, cylinders, and spheres. By mastering these formulas, students can effectively compute the surface area, which is a fundamental concept in geometry.

Learning to use these formulas allows students to engage deeply with mathematical concepts, enabling them to apply their knowledge to solve real-world problems related to surface area. This understanding is critical not only for geometry but also for further studies in mathematics and related fields, such as engineering and physical sciences, where surface area calculations are frequently necessary. Understanding how to apply formulas for area calculations lays a strong foundation for more advanced topics involving geometry and spatial reasoning.
