Q. Find the volume of a pyramid with a square base, where the perimeter of the base is 16.6m and the height of the pyramid is 18.1m. Round your answer to the nearest tenth of a cubic meter.Answer: m3
Identify Formula: Identify the formula for the volume of a pyramid with a square base. The formula is Volume=3Base Area×Height.
Calculate Side Length: Calculate the side length of the square base using the perimeter. The perimeter P of a square is 4 times the side length s, so P=4s. Given P=16.6 meters, we can find s by dividing the perimeter by 4.s=416.6 meterss=4.15 meters
Calculate Base Area: Calculate the area of the square base. The area A of a square is given by A=s2, where s is the side length.A=(4.15meters)2A=17.2225square meters
Calculate Volume: Calculate the volume of the pyramid using the base area and the height. The height h is given as 18.1 meters.Volume = (Base Area×Height)/3Volume = (17.2225 square meters ×18.1 meters) / 3Volume = (311.72725 cubic meters) / 3Volume = 103.9090833 cubic meters
Round Volume: Round the volume to the nearest tenth of a cubic meter. Volume ≈103.9 cubic meters
