a tiny rectangular space inside a computer chip has been measured to be 0.00000256m wide, 0.00000014m long and 0.000275m high. What is the volume of this chip?

Just multiply the 3 numbers together, using this calculator, and you get your answer in cubic m.

Volume = L x W x D  (or H)

So:

2.56 x 10^-6   x   .14 x 10^-6    x   275  x  10^-6    =  98.56  x  10^-6  Cubic Meters  = 0.00009856 cubic meters

=9.856 X 10^-17 cubic meters

My mistake (#2)   agree with #3     98.56 x 10^-18     or 9.856 x 10^-17 is the correct answer
