Question

A lane 160m long and 6m wide is to be paved with bricks of length 8cm and breadth 6cm. Find the cost of bricks that are required at the rate of Rs 1.25 per bricks.

Answer 1

dimension of lane =(160X6)m
area of Lane is (160X6)

dimension of each brick is (8X6)cm =
$\frac{6 \times 8}{100 \times 100} m$


now number of bricks required

$\frac{160 \times 6}{\frac{8 \times 6}{100 \times 100} } m$

160X6X10000
---------------------- => 20X10000=200000
8X6


cost at rs1.25 per brick is

$\frac{200000 \times 125}{100}$
$2000 \times 125$
it's Rs250000(ANS)
