You calculate the volume then multiply by the density of the glass. The volume is 1 x 1 x .006 = .006 cu meters Density depends on glass type but is generally about 2200 kg/cu meter Weight = .006 x 2200 = 13.2 Kg
This problem can be modeled and tested quite easily. Set A can be [X,Y], subset B [X,Y], and subset A [X,Y]. Therefore A and B are equivalent.
(x-8)(x+8)
3 X 8
Yes, -6+x is the same as x-6.

0.00006 or 6x10-5
.00014
6 X 100.
0.006 = (0 x 1) + (0/10) + (0/100) + (6/1000)
.006- Just multiply both sides by the inverse of 10 (1/10) in order to get n by itself. It becomes n=6/100x 1/10 (10/100). The answer becomes 60/10,000 or .006

An expression does not equate to anything. An equation is equal to something. Expression: x+2 Equation: x+4=2x Equivalent expressions: x+2 and 2x-2 if x=4 Equivalent equations: x+4=2x and -x+10=2x if x=4
5(x-y) is also equivalent to 5x-5y

If that is 0.014 ([zero-]point-zero-one-four) million then it does indeed equal 14 thousand: 0.014 million = 0.014 x 1000000 = 14000
Equivalent to what? "3x = 3 + x" is an equation which can be equivalent to other equations, but none is mentioned.
