# Surface Area by Counting Unit Squares Worksheets

Lay the groundwork for finding the surface area of more complex 3D shapes with these introductory worksheets on counting squares. To find the surface area of a rectangular prism, count the number of square units on each of the six faces of the rectangular prism. As the opposite faces of a rectangular prism are congruent, students count the square units of the opposite faces and add them up to compute the surface area. The three-dimensional models in these worksheets allow learners to visualize the rectangular prisms. Surface area is measured in square units, so don't forget to include the square units in your answer.

These pdf worksheets are designed primarily for students of 6th grade and 7th grade.
