What is the surface area of the rectangular prism( in the form of a net) QUICK!!!

The surface area of the rectangular prism is 238 mm².

Solution:

Area of the rectangle = length × breadth

Area of the top rectangle = 11 mm × 5 mm

                                          = 55 mm²

Area of the second rectangle = 11 mm × 4 mm

                                                 = 44 mm²

Area of the third rectangle = 11 mm × 5 mm

                                            = 55 mm²

Area of the bottom rectangle = 11 mm × 4 mm

                                                 = 44 mm²

Area of the left side rectangle = 5 mm × 4 mm

                                                  = 20 mm²

Area of the right side rectangle = 5 mm × 4 mm

                                                    = 20 mm²

Surface area = 55 mm² + 44 mm² + 55 mm² + 44 mm² + 20 mm² + 20 mm²

                     = 238 mm²

The surface area of the rectangular prism is 238 mm².
