what is the surface area of the triangular prism.
the base is 4cm, the height is 3cm and the length is 11 while the side above the base is 5cm
To calculate the surface area of a triangular prism, you need to find the areas of all the individual faces and then add them up.
1. The area of the triangular base:
A = 0.5 * base * height
A = 0.5 * 4cm * 3cm
A = 6cm^2
2. The area of the rectangle side:
A = length * side
A = 11cm * 5cm
A = 55cm^2
3. Since there are two of these rectangle sides, the total area for both sides would be:
2 * 55cm^2 = 110cm^2
4. Add the areas of the two triangle bases and the two rectangle sides to get the total surface area:
6cm^2 (two bases) + 110cm^2 (two sides) = 116cm^2
Therefore, the surface area of the triangular prism is 116 square centimeters.
