What is the surface area of a pyramid with a base area of 25 ft2 and lateral faces each with areas of 15 ft2?

SA = 85 ft²

Step-by-step explanation:

To find the surface area of a 3-D shape, calculate the area of each face, then add them together. We are already given the area of each face.

One lateral face (triangle) is 15 ft².

The base (square) is 25 ft².

From the open pyramid, called a "net", we can see 5 faces in total: four triangles and one square.

Multiply the number of each shape by the area of the shape:

SA = (4 × 15 ft²) + (25 ft²)

SA = 60 ft² + 25 ft²

SA = 85 ft²

3/8 more than flour

I subtracted rice from flour hope this works! good luck
