What is the surface of the triangular prism? Cone on top is 8cm on both sides with dotted line down the middle with the number 6.9cm. The base bottom line is dotted and labeled 8cm. Long rectangle end is 6cm

Answer 1

To find the surface area of the triangular prism, we need to find the areas of all the individual faces and then add them up.

1. The two triangular faces have a base of 8 cm and a height of 6.9 cm. The area of each triangle can be calculated using the formula: (base * height) / 2. So each triangle has an area of (8 * 6.9) / 2 = 27.6 square cm.

2. The rectangular face has a length of 6 cm and a width of 8 cm. The area of the rectangle can be calculated using the formula: length * width. So the rectangle has an area of 6 * 8 = 48 square cm.

So the total surface area of the triangular prism is the sum of the areas of the two triangles and the rectangle: 27.6 + 27.6 + 48 = 103.2 square cm.

Therefore, the surface area of the triangular prism is 103.2 square cm.
