Today's math lesson is about 3D figures and how to calculate the volume of them.
So first let's talk about what 3D figures are and some examples of them. Like a tissue box. Which is a 3D figure because it has three dimensions which are Height, Length, and Width. So let's say the dimension of the tissue box is 3 unit cubes for the height 3 unit cubes for the lenght then for the width it could be 2 unit cubes. whats the volume?
The correct answer is 18 cubic units because to calculate the volume of a 3D figure all you need to do is multiply the dimensions because finding the volume is only figuring out the amount of space inside the 3D figure. That is correct and everything you said is correct. except you forgot to mention that to find the volume of a 3D figure you have to use the formula L*W*H
