Multiples of the above may be found by multiplying the values given 

 by the square of the multiplier. 



Thus, square T * ff inch = ^ x 4 ; the square of4=-4x4 = 16, and 6-45159 

 x 16 - 103-2254 square millimetres, the answer required.

Multiples of the above may be found by multiplying the values given 

 by the cube of the multiplier. 



Thus, 2 cubic millimetres : 2 cubed =2x2x2 = 8, and 61-0239 x 8 

 = 488-1912 cubic ^-J^ inch, the answer required.
