Question

The paint in a certain container is sufficient to paint an area equal to 14.64 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:

The total number of bricks painted out is 300 bricks .

Step-by-step explanation:

Given as :

The area of the container = A = 14.64 square meter

i.e A = 146400 square centimeter

The dimension of the bricks = 11.5 cm × 10 cm × 6 cm

Let The total number of bricks painted out = n bricks

According to question

The total surface area of bricks = 2 ×( length × breadth + breadth × height + height × length )

or, The total surface area of bricks = 2 × (11.5 cm × 10 cm + 10 cm × 6 cm + 6 cm × 11.5 cm )

Or, The total surface area of bricks = 2 × (115 cm + 60 cm + 69 cm )

Or, The total surface area of bricks = 488 square cm

Now,

The total number of bricks painted out = $\dfrac{\textrm area of container}{\textrm surface area of bricks}$

Or , n = $\dfrac{146400}{488}$

i.e n = 300

So, The total number of bricks painted out = n = 300 bricks

Hence, The total number of bricks painted out is 300 bricks . Answer
