Identify Questions: Identify what each question is asking.Filling the prism refers to its volume or capacity.Capacity is the same as volume, how much it can hold inside.Covering the prism refers to its surface area.So, the different measurement is between volume (capacity) and surface area.
Volume Formula: Find the formula for the volume of a rectangular prism.Volume = length×width×height.
Surface Area Formula: Find the formula for the surface area of a rectangular prism.Surface Area = 2(l×w)+2(l×h)+2(w×h).
Lack of Measurements: Realize we don't have the actual measurements of the prism. Without the dimensions, we can't calculate the exact volume or surface area. But we know the formulas are different, so the measurements for filling and covering are different.
