Find the volume of a pyramid with a square base, where the side length of the base is 18.5 in and the height of the pyramid is 10.9 in. Round your answer to the nearest tenth of a cubic inch.
Q. Find the volume of a pyramid with a square base, where the side length of the base is 18.5 in and the height of the pyramid is 10.9 in. Round your answer to the nearest tenth of a cubic inch.
Identify Formula: Step 1: Identify the formula for the volume of a pyramid. The formula is Volume=31×Base Area×Height. Here, the base is a square with side length 18.5 in.
Calculate Base Area: Step 2: Calculate the area of the square base. Area = side length×side length=18.5in×18.5in=342.25in2.
Plug Area and Height: Step 3: Plug the area and height into the volume formula. Volume = (31)×342.25 in2×10.9 in.
Find Volume: Step 4: Perform the multiplication and division to find the volume. Volume = (31)×342.25×10.9=1242.2825 in³. Round this to the nearest tenth: 1242.3 in³.
