Question

The paint in a certain container is sufficient to paint an area equal to 9.375 m². How many bricks of dimension 20m x 7.5m x 9m can be painted out of this container?​

Answer 1

The total surface area of 1 brick X total no. of bricks = volume of paint

=> 2[150 + 180 + 67.5] x no. of bricks = 9.375

=> 795 x No. of bricks = 9.375

=> No = Not even a full brick will be painted

the total area should be => 93750cm²

=> 2[150 + 180 + 67.5] x no. of bricks = 93750

=> 795 x No. of bricks = 93750

=> No of bricks = 118 (approx)
