Since the barn has an air vent taking up some space, Clay needs to calculate the volume of the air vent and subtract it from the total volume of the barn to determine how many cubic feet of oats he can store.
Let's say the air vent has dimensions of 3 feet in length, 2 feet in width, and 1 foot in height. The volume of the air vent can be calculated as:
Volume of air vent = length * width * height
Volume of air vent = 3 ft * 2 ft * 1 ft
Volume of air vent = 6 cubic feet
If the total volume of the barn is 100 cubic feet, Clay can store oats in the barn with a volume of 100 cubic feet - 6 cubic feet = 94 cubic feet.
Therefore, Clay can store 94 cubic feet of oats in his barn after accounting for the volume of the air vent.
Note: figure not drawn to scale.
Clay's oat barn has an air vent in the shape of a rectangular prism lengthwise through the barn. Clay is able to use the entire volume of the barn, except for the air vent, to store oats. He has decided to fill the barn to capacity to be prepared for the upcoming winter and planting season.
Clay called the Farmers CO-OP and ordered
cubic feet of oats.
