Find the total surface area of the net below.
Solnce55 [7]

Total surface area of the triangular prism is  81.6 square m.

Step-by-step explanation:

  • b = 3 m
  • h = 2.6 m
  • p = 3+ 2.6 +2.6=  8.2
  • H = 9 m
  • SA = bh + pH

    = 3 × 2.6 + 8.2 ×9

    = 7.8 + 73.8

    = 81.6

  • Therefore,
  • SA = 81.6 square m
  • Total surface area of the triangular prism is  81.6 square m.

How to change 9.15 to a fraction
bagirrra123 [75]
The 1 is in the tenths place and the 5 is in the hundredths place, so we know that the denominator will be 100.
The numerator will be 15, since that is the decimal.

9 \frac{15}{100}

To simplify, first find the GCF between 15 and 100.

15:1,3,5,15 \\ 100:1,2,4,5,10,20,25,50,100 \\ common:1,5 \\ GCF:5

Now, to get the fully simplified mixed number, divide the numerator and denominator both by the GCF.

9 \frac{15:5}{100:5}  \\  \\ 9 \frac{3}{20}

To convert the mixed number into an improper fraction, multiply the whole number by the denominator and add it to the numerator, keeping the denominator. This will be your final answer.

\frac{9*20+3}{20}  \\  \\  \frac{180+3}{20}  \\  \\  \frac{183}{20}
