volume of cube=side^3
=4×4×4
=64m²
volume of rectangular piece=l×b×h
=20×10×5
=1000cm²
=10m²
no. of rectangular pieces can be cut from the cube=64/10
=6.4
hence, final answer is 6.4 pieces can be cut from the cube.

Step-by-step explanation:
required number of block
=volume of cube/volume of cuboid
=4m×4m×4m/20cm×10cm×5cm
=400×400×400/20×10×5
=64000000/1000 = 64000=ans (in this process we have multiplied 400 because 1metre = 100cm)
