Ok, so:
First of all, we're going to find the volume of the cube, and then, we're going to rest the volume of the cone from the cube, and then we'll obtain the result.
So, the volume of a cube is given multiplying its height, its large and its width.
So, the volume of the cube will be (6mm)(6mm)(6mm), which is equal to 216mm^3.
Now, we have to find the volume of the cone.
This volume can be calculated using this equation:
Vcone = (π*r^2*h)/3.
where r is the radius and h is the height.
So, if we replace:
Vcone = (π*(2^2)*6)/3.
So, Vcone is 8π mm^3.
Now, we have to find the remaining volume!
This is 216mm^3 - 8π mm^3.
And that's equal to: 190.867mm^3
