Question

1. A granite block of 2m x5m x 3m size is cut into 5cm thick slabs
of 2m x 5m size. These slabs are laid over a 2m wide pavement.
What is the length of the pavement that canbe covered with
these slabs?
(a) 100 m
(b) 200m
(c) 300 m
(d) 500 m​

Answer 1

Answer:

300 m

Step-by-step explanation:

number of slabs will be vol. of granite block÷vol.of one slab = 200×500×300/5×200×500 = 60 slabs.

now these 60 slabs are laid down on a pavement of 2m width.then, the area of pavement will be equal to the total area of 60 slabs.

2×l = 60×5×2 ; 2l = 600; l = 600÷2 = 300m.
