The width of the rectangular parallelepiped is 5 1 / 30cm, its length is 7 1/2 more than its width, and its height is 30% of the length. Calculate the volume of the parallelepiped.

To solve this problem, remember that the volume of a rectangular parallelepiped is equal to the product of length and width and height. Let’s calculate what is the length of the rectangular parallelepiped.

5 1/30 + 7 1/2 = 12 8/15 cm.

Let’s calculate what the height of the rectangular parallelepiped is. To find the percentage of the number, you need to multiply this number by the percentage and divide by one hundred.

12 8/15 * 30/100 = 188/15 * 30/100 = 376/100 = 3.76 cm.

Let’s calculate what the volume of a rectangular parallelepiped is equal to.

V = 12 8/15 * 3 76/100 * 5 1/30 = 188/15 * 376/100 * 151/30 = 10673888/45000 = 237 8888/45000 = 237 2222/11250 = 237 1111/5625 cc …

Answer: 237 1111/5625 cc.
