Given, To find :
→ How many rectangular slabs of 10 cm × 8cm are required to cover the floor of a hall of 12m × 10m?
ㅤㅤ
Formula :
★ Area = Length × Breadth.
★ Number of labs = Area of floor/Area of all labs.
ㅤㅤ
Calculations :
→ Area = 10 × 8
→ Area = 80 cm² = 0.008 m²
ㅤㅤ
→ Area = 12 × 10
→ Area = 120
ㅤㅤ
→ Number of labs = 120/0.008
→ Number of labs = 15000 labs.
ㅤㅤ
★ Therefore, 15000 is total number of labs.
