In a rectangular parallelepiped, the length is 19 cm, is 5 cm more than the width and 5 cm less than the height. Find all the dimensions of a rectangular parallelepiped and its volume. In a rectangular parallelepiped, the width of 15 inches is 2 inches less than the length and 2 times less than the height. Find all measurements and the area of the upper base.

1) Find the dimensions of the parallelepiped. The length is 19 cm.

The width is 19 cm – 5 cm = 14 cm.The height is 19 cm + 5 cm = 24 cm.

Let’s find the volume of this rectangular parallelepiped.

V = 19 cm * 14 cm * 24 cm = 6384 cm³.

2) In the second parallelepiped, the width is 15 dm. Let’s find the length and height.

The length is 15 dm + 2 dm = 17 dm.

The width is 15 dm * 2 = 30 dm.

The area of the upper base is equal to:

15 dm * 17 dm = 255 dm².

Answer: 1) width 14 cm, length 19 cm, height 24 cm, volume 6384 cm³.

2) width 15 dm, length 17 dm, height 30 dm, area of the upper base 255 dm².
