Calculate the volume of a rectangular parallelepiped whose base area and height are equal

Calculate the volume of a rectangular parallelepiped whose base area and height are equal: a) 18 cm, 16 cm, 5 cm, c) 16 cm, 23 cm, 25 cm.

The volume of a parallelepiped is the product of its height, width and length.
V = abc.
All the data is known, you just need to sequentially substitute the numerical values into the formula.
a) 18 × 16 × 5 = 1440 cm³;
b) 16 × 23 × 25 = 9200 cm³.
Answer: a) 1440 cm³; b) 9200 cm³.
