first let us find the volume of each block
it is 25x10x8 cm
which is equal to 2000cm^3
the volume of the pit is 200x200x200 cm
which is equal to 8000000cm^3
so,the number of bricks that can fit in is 8000000/2000 which is 4000
so, 4000 BRICKS CAN BE FIT IN

Answer:
4000 Bricks
Step-by-step explanation:
How many bricks measuring 25 cm x 10 cm x 8 cm can be made from the earth dug out from a cubical pit measuring 2 m in length?
Volume of Cubical pit = 2³ = 8 m³
= 8 * 100³ cm³ ( 1 m = 100 cm)
= 8 * 10⁶ cm³
Volume of a brick = 25 * 10 * 8 = 2000 cm³
= 2 * 10³ cm³
Numbers of bricks that can be made = Volume of Earth / Volume of a Brick
= (8 * 10⁶ )/ (2 * 10³)
= 4 * 10³
= 4000
4000 Bricks can be made
