To solve, follow the formula Volume = Length · Height · Width. If you are solving without a calculator, simply multiply the length and the height first, then multiply the product of that by the width, 2 / 3. V = 10 · 9 · 2/3 V = (10 · 9) 2/3 V = 90 · 2/3 <span>V = 60 in.³ </span> Hope this helps. Good luck! :)
