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

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
