Answer: 0.0028 m^3
Explanation: In order to calculate the volume in cubic meters, you must first convert your measurements into meters, using the conversion factor:
1 mm = 0.001 m
this leaves you with dimensions of .25m, .224m, and 0.05m
from here you calculate the volume by multiplying the length, width, and thickness all together:
0.25m * 0.224m * 0.05m = 0.0028 m^3
