Dear Parents and Students,

We are assigning this work in an effort to prepare our students for a successful school year,

and to provide them with an appropriate way to assist them retaining basic mathematical knowledge

This work is not intended to be completed in one sitting. It is intended to be completed at a

steady pace throughout the summer. It will be the first grade to be entered in the grade book upon

returning to school. All exercises have space to show calculations, and calculator answers will not be

accepted. All work must be shown to receive the credit.

The students may be assisted, and we encourage you use the Glossary included in the

school’s website, on Mrs. Linette Prats’ page. Additionally, each section begins with examples to be

followed, and you may refer to the provided FCAT 2.0 Reference Sheet.

Remember that the educational process is a team effort and we all play vital roles- teachers,

parents, and students.

• Objective: Determine the surface area of geometric solids using rectangular prisms.

The sum of the areas of all the surfaces, or faces, of a three-dimensional figure is the surface area. The surface area S of a

rectangular prism with length l, width w, and height h is found using the following formula:

S = 2lw + 2lh + 2wh

Example: Find the surface area of the rectangular prism.

You can use the net of the rectangular prism to find its surface area. There are 3 pairs of congruent faces on a rectangular prism:

top and bottom

front and back

two sides Faces Area top and bottom (4 • 3) + (4 • 3) = 24 front and back (4 • 2) _ (4 • 2) =16 two sides (2 • 3) + (2 • 3) = 12 Sum of the areas 24 + 16 + 12 = 52

Alternatively, replace l with 4, w with 3, and h with 2 in the formula for surface area. S = 2lw + 2lh + 2wh S = 2 • 4 • 3 + 2 • 4 • 2 + 2 • 3 • 2 Follow order of operations. S = 24 + 16 + 12 S = 52 So, the surface area of the rectangular prism is 52 square meters.

Find the surface area of the rectangular prisms below. Round to the nearest tenth, if necessary.
