THE CORRECT ANSWER IS 57 CM³
Explanation:
Let's consider the vertical block first, having height 9 cm, length 1 cm, width 5 cm.
Hence the volume of that block = l.w.h = 9×5×1 = 45 cm³
Coming to the horizontal block, having height 4 cm, width 3cm, & length 1 cm.
Hence the volume of that block will be = 4×3×1 = 12 cm²
The total volume of irregular figure = Volume of vertical block + horizontal block = 45+12 = 57 cm³
