The room is 5 m long, 4 m wide, 2.5 m high. What is the volume of the room?

It is known:
Room length = 5 m,
Width = 4 m;
Height = 2.5 m.
Let’s find the volume of the room.
Decision:
In order to find the volume of a room, you need to multiply the length, width and height by each other, that is, find their product.
We get the volume of the room:
V = 5 m * 4 m * 2.5 m = 5 * 4 * 2.5 m ^ 3 = 20 * 2.5 m ^ 3 = 20 * 5/2 m ^ 3 = 20/2 * 5 m ^ 3 = 10 * 5 m ^ 3 = 50 m ^ 3;
This means that the volume of the room is 50 m ^ 3.
Answer: V = 50 m ^ 3.
