l=15m.b=6m.h=5dm.volume of the cuboid

5dm to m =0.5m. Therefore volume =L * B * H. =15*6*0.5m. =45m^3

To find the volume of a cuboid, you need to multiply its length, width, and height. Given that the length (l) is 15 meters, the width (b) is 6 meters, and the height (h) is 5 decimeters, we need to convert the height to meters to maintain uniform units.

Since 1 decimeter (dm) is equal to 0.1 meters, we can convert the height from decimeters to meters by multiplying it by 0.1:
h = 5 dm * 0.1 = 0.5 m

Now that we have all three measurements in meters, we can calculate the volume of the cuboid by multiplying them:
Volume = l * b * h = 15 m * 6 m * 0.5 m = 45 m^3

Therefore, the volume of the cuboid is 45 cubic meters.
