Question

How many pieces of stone slabs each 26 cm long and 10 cm broad will be required to lay a path 260 m long and 15 m wide.

• A. 15,000
• B. 1,20,000
• C. 2,50,000
• D. 1,50,000

Answer 1

The correct option is D 1,50,000

For each slab,
length = 26 cm, breadth = 10 cm

From the given dimensions we can see that each slab is in the shape of a rectangle.

Therefore, the area of a slab = length × breadth
= 26 cm × 10 cm
= 260 cm²

For the path,
length = 260 m, breadth = 15 m

Therefore, the area of the path
= (260 × 15) m²
= 260 × 15 × 10000 cm²
[$\because$ 1 m² = 10000 cm²]

Therefore, number of slabs required

$=\frac{Areaofpath}{Areaofeachslab}$

$=\frac{260\times 15\times 10000}{260}$

$=150000$

Therefore, 1,50,000 slabs will be required.
