Q. Find the volume of a pyramid with a square base, where the perimeter of the base is 9.4ft and the height of the pyramid is 6.2ft. Round your answer to the nearest tenth of a cubic foot.Answer: ft3
Find Side Length: First, we need to find the length of one side of the square base. Since the perimeter of a square is the sum of all its sides, and a square has four equal sides, we divide the perimeter by 4. Perimeter of the base = 9.4ftSide of the square base = Perimeter /4Side of the square base = 9.4ft/4
Calculate Side Length: Now, calculate the side length of the square base.Side of the square base = 49.4ftSide of the square base = 2.35ft
Calculate Base Area: Next, we calculate the area of the square base by squaring the side length.Area of the base = (Side of the square base)Area of the base = (2.35ft)2
Calculate Volume Formula: Perform the calculation for the area of the base.Area of the base = (2.35ft)2Area of the base = 5.5225ft2
Calculate Volume: Now, we use the formula for the volume of a pyramid, which is (31)×(base area)×(height). Volume of the pyramid = (31)×(base area)×(height) Volume of the pyramid = (31)×5.5225 ft2×6.2 ft
Final Volume Calculation: Finally, calculate the volume of the pyramid.Volume of the pyramid = (1/3)×5.5225 ft2×6.2 ftVolume of the pyramid = 1/3×34.2395 ft3Volume of the pyramid = 11.41317 ft3
Round Volume: Round the volume to the nearest tenth of a cubic foot. Volume of the pyramid ≈11.4 ft3
