Answer:

  • 48 in

-------------------

The volume of a pyramid is 1/3 of the product of the base area and height.

  • V = Bh/3

Find the area of the base:

  • 480 = B*10/3
  • B = 480*3/10
  • B = 144

The base is the square, so each side is the square root of the base area:

  • a = √B
  • a = √144
  • a = 12

The perimeter of the base is:

  • P = 4a
  • P = 4(12)
  • P = 48

Answer: 48 inches

Step-by-step explanation:

480*3=1440

1440/10=144

each side: 12

12*4=48 inches
