Question 86774: Two blocks, each of length x, width x+4, and height x, are cut out of a block of length 3x+4, width x+4, and height x. All dimensions are given in centimeters. Find the volume of the resulting solid.
Since V= L*W*H, wouldn't I take the volume of the original block and then subtract the volume of what was cut out??? Where I seem to be having trouble, is the fact that there were 2 blocks cut out. Would I have to double the lenght, width and height in order to figure out the volume that was cut out and then subtract it from the volume of the original block??? Thank you for your help with this one.

you need to have some fix number for one of the volumes, otherwise the answer will only will only be abstractive.
The remaining (resulting) volume would
W*H*L = V(remaining)
W=x+4
H=x
L=(3x+4)-2x
