Answer:
→ 12,500 bricks .
Step-by-step explanation:
Case 1 .
→A wall is to be built using bricks of dimensions 20cm × 16cm × 8cm.
Length = 20 cm .
Breadth = 16 cm .
Height = 8 cm .
∵ Volume of brick = LBH .
= ( 20 × 16 × 8 )cm³ .
= 2560 cm³ .
Case 2 .
Volume of wall .
Length = 10 m = 1000 cm .
Breadth = 5 m = 500 cm .
Height = 64 cm .
∵ Volume of wall = LBH .
= ( 1000 × 500 × 64 ) cm³ .
= 32000000 cm³ .
∵ No. of bricks = ( Volume of wall ) / ( Volume of brick )
= 32000000 cm³ / 2560 cm³ .
= 12,500 bricks .
Hence, it is solved .
