Volume of a pyramid 10 feet by 10 feet base and height of 8.5 feet

The formula for the volume of a pyramid is: Volume = (1/3) * (Area of the base) * (Height of the pyramid) You stated that the pyramid has a 10 by 10 base, so the "area of the base" is 100 squared feet. Also, you stated that the "height of the pyramid" is 8.5 feet. So, Volume = (1/3) (100 squared feet) (8.5 feet) V = (1/3) (850 cubic feet) V=283.33333 ... cubic feet
