Answer:
264 cubic metres
Explanation:
We need to find the volume of both aquariums and add them up.
The aquariums are shaped as rectangular prisms.
The volume of a rectangular prism is:
V = L * W * H
where L = length, W = width, H = height
The first aquarium is 6 m long, 4 m wide, and 2 m high. Its volume is:
V = 6 * 4 * 2 = 48 cubic metres
The second aquarium is 8 m long, 9 m wide and 3 m high. Its volume is:
V = 8 * 9 * 3 = 216 cubic metres
The amount of space the turtles have is therefore:
V = 48 + 216 = 264 cubic metres
