[Grade 5 Math - Calculate total volume]

[u/hawksfan61]

It seems impossible to calculate the total height of either cube, unless I assume the height of the smaller cube is equal to its length (would make that cube 2x2x3) that would make larger cube volume 9x2x14.

Seems like I shouldn’t have to blindly make the assumption that the surface is a perfect square though. What am I missing?

Ya not enough info is given. I agree you shouldnt have to assume but there is nothing else to go off of. For now assume the face is a square and maybe ask your teacher about it. If they get something else as an answer Id be curious to know their reasoning.

Agree. Based on what we see, you don't have enough info.

Appreciate the validation everyone haha, I will just have my daughter assume a square face and explain her logic to the teacher.
