Luis models the volume of a popcorn box as a right rectangular prism. Its dimensions are 321 in by 2 in by 643 in. How many cubic inches of popcorn would it hold when it is full? Round your answer to the nearest tenth if necessary.
Q. Luis models the volume of a popcorn box as a right rectangular prism. Its dimensions are 321 in by 2 in by 643 in. How many cubic inches of popcorn would it hold when it is full? Round your answer to the nearest tenth if necessary.
Convert to Improper Fractions: To find the volume of a right rectangular prism, we use the formula Volume=length×width×height. The given dimensions of the popcorn box are 3(21) inches by 2 inches by 6(43) inches. We need to convert the mixed numbers to improper fractions to make the multiplication easier.
Calculate Volume: First, convert 3(1/2) inches to an improper fraction. 3(1/2) inches is the same as (3×2+1)/2 inches, which equals 7/2 inches.
Simplify Multiplication: Next, convert 6(43) inches to an improper fraction. 6(43) inches is the same as (6×4+3)/4 inches, which equals 427 inches.
Divide to Find Volume: Now, multiply the dimensions together to find the volume. The volume V is given by V=length×width×height, so V=(27) inches ×2 inches ×(427) inches.
Round to Nearest Tenth: Simplify the multiplication. First, multiply the numerators together: 7×2×27. Then, multiply the denominators together: 2×1×4.
Round to Nearest Tenth: Simplify the multiplication. First, multiply the numerators together: 7×2×27. Then, multiply the denominators together: 2×1×4.The multiplication of the numerators gives us 7×2×27=14×27=378. The multiplication of the denominators gives us 2×1×4=8.
Round to Nearest Tenth: Simplify the multiplication. First, multiply the numerators together: 7×2×27. Then, multiply the denominators together: 2×1×4.The multiplication of the numerators gives us 7×2×27=14×27=378. The multiplication of the denominators gives us 2×1×4=8.Now, divide the result from the numerators by the result from the denominators to get the volume in cubic inches: 8378 cubic inches.
