Final answer:
The volume of the cuboid is 4 cubic meters, not 400 cubic meters.
Step-by-step explanation:
A cuboid measures 4m by 2m by 50cm. To find the volume of a cuboid, we multiply its length, width, and height. The volume formula for a cuboid is V = l x w x h. So, the volume of the given cuboid is 4m x 2m x 50cm. However, we need to convert the height to meters because the other measurements are given in meters.
To convert 50cm to meters, we divide it by 100 since there are 100cm in a meter. So, 50cm = 50/100 = 0.5m. Now we can calculate the volume: V = 4m x 2m x 0.5m = 4 x 2 x 0.5 = 4m³.
Therefore, the volume of the given cuboid is 4 cubic meters, not 400 cubic meters.
