| The aquarium has the shape of a rectangular parallelepiped. Its base area is 942 cm2, and its height is 3 dm. 5 cm.What mass of water can this aquarium hold if it is known that 1 cm3 of water has a mass of 1 g.
Let’s express the height in centimeters:
1 dm = 10 cm;
3 dm 5 cm = 3 * 10 + 5 = 30 + 5 = 35 cm.
Formula for the volume of a rectangular parallelepiped:
V = Sо * h, Sо – base area, h – parallelepiped height.
Let’s calculate the volume of the aquarium:
942 * 35 = 32970 cm ^ 3 – the volume of the aquarium.
Let’s calculate how much water this aquarium can hold:
32970: 1 = 32970 g = 32 kg 970 g is the mass of water that this aquarium can hold.
Answer: the mass of water that this aquarium can hold is 32970 g = 32 kg 970 g
