What is the volume of a chest that is 20 inches by 10 inches by seven and one tenth inches?
20 * 10 * 7.1 = ?
1420
To find the volume of a rectangular chest, you need to multiply its length, width, and height together.
In this case, the length is 20 inches, the width is 10 inches, and the height is 7 and one tenth inches.
To multiply the dimensions together, you can follow these steps:
1. Convert the mixed fraction (7 and one tenth) into an improper fraction.
A mixed fraction can be expressed as 7 + 1/10, so the improper fraction is (7*10 + 1)/10 = 71/10 inches.
2. Multiply the length, width, and height together:
Volume = Length * Width * Height
Volume = 20 inches * 10 inches * (71/10) inches
3. Calculate the result:
To multiply mixed numbers, multiply the whole numbers together, multiply the fractions together, and then sum the two products.
Volume = 20 * 10 * 71/10 = 14,200 cubic inches
Therefore, the volume of the chest is 14,200 cubic inches.
