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

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
