How to find the tsar of a cuboid plus a triangular prism

To find the total surface area (TSA) of a cuboid plus a triangular prism, you will need to calculate the individual surface areas of the two shapes and then add them together.

1. Surface Area of Cuboid:
The formula to find the surface area of a cuboid is given by:
TSA = 2(lw + lh + wh)
Where:
- l, w, and h are the length, width, and height of the cuboid.

2. Surface Area of Triangular Prism:
The formula to find the surface area of a triangular prism is given by:
TSA = 2(base area of triangle) + (perimeter of triangle) * (height of prism)
Where:
- Base area of triangle = 0.5 * base * height of triangle
- Perimeter of triangle = sum of all three sides of the triangle

Once you have calculated the surface areas of the cuboid and triangular prism separately, you can add them together to find the total surface area of the cuboid plus triangular prism.

TSA = Surface Area of Cuboid + Surface Area of Triangular Prism
