A tent in the shape of a triangular prism is made using the following piece of fabric. Diagram shows the net of a triangular prism. Its two identical triangular bases have all sides of length 4 feet and heights of 3 decimal point 46 feet. Its three rectangular sides have lengths of 6 feet and heights of 4 feet. The 4x6 is 24 and the triangles are 6.92 that can be made a fraction 92/100 then divided down to 23/25 so each of the triangles are 6 23/25 so that times 2 is 13 21/25

Find the surface area of the fabric. Explain your reasoning. Then 24 times 3 is 72 so 85 and 21/25

This was quite confusing so if you can give some explanation to the answer, please that'd help
