Answer 1

6. C

7. 105 ft²

Step-by-step explanation:

The square pyramid has a square base with a side's length equal to 5 ft and a slant height equal to 8 ft.

Now, the only option that shows a square with a side length equal to 5 is C. So, the right net is C.

Then, the amount of fabric depends on the area of the net. The area of the net is equal to the area of the square added to the area of the triangles.

The area of the square is:

Area = side x side = 5 x 5 = 25 ft²

The area of the triangles is:

Area = 1/2 x base x height = 1/2 x 5 x 8 = 20 ft²

Then, the total area of the net is:

Total Area = 25 ft² + 4( 20 ft²)

Total Area = 25 ft² + 80 ft²

Total Area = 105 ft²

So, Frank needs 105 ft² of fabric to make the fort.
