To the nearest tenth, which is the best estimate for the volume of the given pyramid

Step-by-step explanation:

Keywords:

perimeter, square, base, pyramid, kilometers, side

For this case we must find the perimeter of the base of a square pyramid, whose side of the square measures 160m. In addition, the measure obtained must be converted to kilometers. So, we have by definition the perimeter of a square is the sum of its sides, which is equivalent to , where "l" is the side of the square.

If, then:

Thus, the perimeter of the base of the pyramid is 640m.

On the other hand, by definition:

By making a rule of three we have:

1Km ---------> 1000m

x --------------> 640m

Where "x" represents the perimeter of the base of the pyramid in Km.

Thus, the perimeter of the base of the pyramid is 0.64Km

The perimeter in kilometers is 0.64
