Answer:
Step-by-step explanation:
The surface area of the triangular prism consists of three rectangles and two triangles.
Rectangle One - 5 x 12 = 60 cm^2
Rectangle Two - 4 x 12 = 48 cm^2
Rectangle Three - 3 x 12 = 36 cm^2
Triangles - 2 x 1/2 x 3 x 4 = 12 cm^2
Thus, the total surface area of the solid is
The sum of the arithmetic series 6 8 10 12 14 16 18 20 22 24 26 is 176
<h3>How to determine the sum of the series?</h3>The series is given as:
6 8 10 12 14 16 18 20 22 24 26
The above series is an arithmetic series with the following parameters:
First term, a = 6
Last term, L = 26
Number of terms, n = 11
The sum of the series is calculated using:
This gives
Evaluate
Hence, the sum of the arithmetic series 6 8 10 12 14 16 18 20 22 24 26 is 176
