How many bricks of length 20cm ,breadth 8 cm and height 6cm will be needed to build a wall of length 10 m, breadth 6 cm and height 2 m?
Answers
Answer:
1,250 bricks
Explanation:
Length of one brick = 20 cm
Breadth of one brick = 8 cm
Height of one brick = 6 cm
Volume of one brick = l × b × h
= 20 × 8 × 6
= 960 cm
Length of wall = 10 m = 1,000 cm
Breadth of wall = 6 cm
Height of wall = 2 m = 200 cm
Volume of wall = l × b × h
= 1000 × 6 × 200
= 12,00,000 cm
Number of bricks = Volume of wall/ Volume of one brick
= 12,00,000/ 960
= 1,250 bricks
Answer:
1,250
Step-by-step explanation:
length of one brick 20cm
bredth of one brick 8cm
hiegth of one brick 6cm
volume of one brick l × b ×h
960
L of Wall 10m 1,000
B of Wall 6cm
H of Wall 2m 200cm
volume of Wall
1000 × 6× 200
12,00,000
