c) 45%

Let the initial length=10, breadth=10 and height=10 units, so volume=10x10x10=1000 unit².
When length, breadth, and height of a cube are increased by 10%, 10%, and 20% respectively, then New lenght=11, breadth=11 and height=12 units, so volume=11x11x12=1452 unit².
Hence % change in volume=(1452 - 1000)x100/1000 = 45.2 ~ 45
