option D
Given;
larger cube edge length - 3x+2 units
smaller cube edge length - 2x-1 units
We know that volume of a cube = (Edge of the cube)3
volume of larger cube = (3x+2 )³
=27x³+8 +54x²+36x
volume of smaller cube=(2x-1)³
=8x³-1 -12x²+6x
Volume difference = volume of larger cube -volume of smaller cube
volume difference =( 27x³+8+54x²+36x)-(8x³- 1 - 12x²+6x)
= 19x³+9+66x²+30x
=19x³+66x²+30x+9
Hence volume of larger cube is greater by (19x³+66x²+30x+9)
