Determine the volume of water required to fill the aquarium. Aquarium dimensions b = 3 dm a = 6 dm c = 4 dm.

Given:

a = 6 decimetres = 0.6 meters – the length of the aquarium;

b = 3 decimetres = 0.3 meters – the width of the aquarium;

c = 4 decimetres = 0.4 meters – the height of the aquarium.

It is required to determine V (cubic meter) – the volume of water required to fill the aquarium.

Since the aquarium is a geometric figure – a rectangular parallelepiped, we will find the volume of the aquarium:

V = a * b * c = 0.6 * 0.3 * 0.4 = 0.072 cubic meters (72 liters).

Answer: To fill an aquarium, you need a volume of water equal to 0.072 cubic meters (72 liters).
