Find the total surface area of this triangular prism 8cm 2cm 17cm 15cm

The total surface area of the triangular prism = 200 cm²

Solution:

Area of triangular face =

                                      = 60 cm²

Area of 2 triangular faces = 2 × 60 = 120 cm²

Area of sloping rectangular side = length × width

                                                      = 17 × 2

                                                      = 34 cm²

Area of back rectangular side = length × width

                                                  = 8 × 2

                                                  = 16 cm²

Area of bottom side = length × width

                                  = 15 × 2

                                  = 30 cm²

Total surface area = 120 cm² + 34 cm² + 16 cm² + 30 cm²

                               = 200 cm²

The total surface area of the triangular prism = 200 cm²

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.

correct me if i'm wrong and if it is i'm truly sorry.
