How many feet are a 108 12inch by 8inch block?

To find the volume of a block measuring 108 inches by 12 inches by 8 inches, first convert the dimensions to feet. There are 12 inches in a foot, so the dimensions in feet are 9 feet (108 inches ÷ 12), 1 foot (12 inches ÷ 12), and ( \frac{2}{3} ) feet (8 inches ÷ 12). Therefore, the volume of the block in cubic feet is ( 9 \times 1 \times \frac{2}{3} = 6 ) cubic feet.
