A marble tile measures 10 cm x 12 cm how many tiles will be required to cover a Wall of size 3 m x 4 m also find the cost of the total cost of the titles at the rate of ₹ 2 per tile .
Answers
Answer:
Step-by-step explanation:
Total Cost of tiles = Cost of one tile * No of tiles required
No of tiles required = Total area of wall / Area of 1 tile
Area of one tile = 12 * 10 = 120 cm²
1 m = 100cm, 3m = 300cm and 4m = 400cm
Area of the wall = 400 * 300 = 120000cm²
No of tiles required = 120000/120 = 1000 tiles
Total cost of tiles = 1000 * 2=2000

A marble tile measures 10 cm x 12 cm how many tiles will be required to cover a Wall of size 3 m x 4 m also find the cost of the total cost of the titles at the rate of ₹ 2 per tile .
Area of wall = 3m × 4m
= 12sq m
= 120000sq cm
Area of tiles = 10cm × 12cm
= 120sq cm
No. of tiles use to cover = 120000/120
= 1000 tiles
cost of tiles = 1000 × ₹2
= ₹2000
