To find the volume of the cuboid room, we need to multiply its length, width, and height.
Given:
Length of the room = 6 m
Width of the room = 75% of the length = 75/100 * 6 = 4.5 m
Height of the room = 2/5 of the length = (2/5) * 6 = 2.4 m
Volume of the room = Length * Width * Height
Substituting the given values:
Volume = 6 * 4.5 * 2.4 = 64.8 cubic meters
Answer: The room has a volume of 64.8 cubic meters.
