The formula for finding volume of a rectangular prism is V = l * w * h Where l is length = 6yd w is width = 1 2/3 ( 1 2/3 can be rewritten as 5/3) h is height = 3 1/3 ( 3 2/3 can be rewritten as 11/3) we then want to plug them into our formula V = 6 * 5/3 * 11/3 We then multiply our fractions so we can just multiply across to get V = 30/3 * 11/3 V = 330/9 Which we can simplify and get V = 110/3 yd^3
