Susan made a block with small cubes of 5 cubic cm volume to make a block 7 small cubes long, 7 small cubes wide and 6 small cubes deep. She realise that she has used more small cubes than she really needed. She realised that she could have glued a fewer number of cubes together ot look like a block with same dimensions, if it were made
Choose the correct choice from the following:	A) 194	B) 195	C) 196	D) 197	E) 198
Volume of cube of dimensions 7 7 6 is  7*7*6= 
<gadget id="calculator"> 7*7*6</gadget>
<output>294</output>
294   If it were to look hollow the imaginary inside cube volume is to be deducted   which is  (7-2)*(7-2)*(6-2)= 
<gadget id="calculator"> (7-2)*(7-2)*(6-2)</gadget>
<output>100</output>
100 (Here 2 is deducted because the inside cube which has to be hollow is 2 cubes more on every dimension)   so minimum number of cubes required to make hollow cube is   294-100=
