The height of a rectangular parallelepiped is 20 cm, which is 4 cm less than its length and 5 times its width. Calculate the volume of this parallelepiped.
1) 20 – 4 = 16 cm – the length of the parallelepiped. We subtract less AT 4.
2) 20: 5 = 4 cm – the width of the parallelepiped. Divide by 5.
3) V = a * b * c – the volume of the parallelepiped.
a = 16 cm, b = 4 cm, c = 20 cm
V = 16 * 4 * 20 = 16 * 80 = 1280 cm²
Answer: the volume of the parallelepiped is V = 1280 cm².
