Question

the paint in a certain container is sufficient to paint paint and equal to 14.6 per metre square how many bricks of dimension 11.5 cm into 10 cm and 26 CM can be painted out of this container​

Answer 1

Answer:

Surface area of one brick = 2(l b + b h + h l)

= 2(22.510 + 107.5 + 7.522.5) cm2

= 2[225 + 75 + 168.75] cm2

= 2[300 + 168.75] cm2

= 937.5 cm2

Number of bricks that can be painted =

= 100

Step-by-step explanation:

Answer 2

Answer:

100 bricks

Step-by-step explanation:

Given

L= 11.5cm

b = 10cm

h = 26cm

we know that total surface area of cuboid = 2(lb +bh + lh)

so

surface area of cuboid= 2(11.5*10+10*26+26*11.5)

Now

Number of bricks = 2(11.5*10+10*26+26*11.5)/14.6

= 100 bricks
