Question

the paint in a certain container is sufficient to paint an area equal to 14.64 m sq. How many bricks of dimensions 11.5cm×10cm×6cm can be paintedout of this container?
(a) : 15000
(b) : 30000
(c) : 3000
(d) : 300000​

Answer 1

Answer:

ans: 300 so none of the above options

Step-by-step explanation:

we have to find the surface area of one brick then we can find how many bricks can be painted

so surface area = 2(lb+bh+lh)

since brick will be In the shape of a cuboid

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

2(115+60+69)

2(244)=488cm^2

so the surface is in cm^2 so convert that into m^2

we know that 1m =100cm

so 1m*1m = 100cm*100cm

so

surface area of one brick = 488/10000 m^2= 0.0488m^2

so the paint will come for = 14.64/0.0488= 300 bricks
