Ok so 2 dice the probability means (desired outcomes)/(total possible outcomes)
one way is to list all outcomes and find the desirable ones (I will list and find product and bold all numbers less than 13) product of 2 numbers means multiply fyi
Assuming the 2,6,1 are length, width and height we can use the formula Volume= length • width • height. When you plug those in you will get 2•6•1= 12. The volume is 12 cubic millimeters. Or 12 cubed
