Question

15. The paint in a certain container is sufficient to paint an area equal to 1464 m2. How many bricks of
dimensions 11.5 cm x 10 cm x 6 cm can be painted out of this container?
​

Answer 1

Answer:

30,000 Bricks

Step-by-step explanation:

Coverage of paint in the container = 1464 $m^{2}$

Total surface area of 1 brick =  2(lb+bh + lh)

But length=l=11.5 cm

Breadth=b=10 cm

Height=h=6cm

:.Total surface area of brick=

2(11.5*10+10*6+6*11.5)

=2(115+60+69)

=2(244)

=488 sq.cm

= 0.0488 $m^{2}$

No. Of brick painted = 1464 / 0.0488

30,000 Bricks

If the Coverage of Paint is 1464 $cm^{2}$, the no of bricks can be painted

= 1464 / 488

= 3 Bricks
