how many bricks of 20 CM length 10 cm breadth 4 cm height are required to make a cube whose each side is 2 metre?
Answers
Answer:
Step-by-step explanation:
TOTAL SURFACE AREA OF BRICK = 2[ LB+BH+LH]
= 2X [200+40+80]
= 2X 320
= 740 CM^2 = 7.4M^2
TSA OF CUBE = 6A^2
= 6X 4
= 24M^2
THERE FORE BRICKS REQUIRED = TSA OF CUBE
---------------------
TSA OF BRICK
= 24/7.4
= 4 BRICKS APPROX
