 Hello and welcome to the session. My name is Mansi and I am going to help you with the following question. The question says the paint in a certain container is sufficient to paint an area equal to 9.375 meter square. How many breaks of dimensions 22.5 centimeter into 10 centimeter into 7.5 centimeter can be painted out of this container. So let us start with the solution to this question. Now what we do in this question is first of all we find surface area of one brick then it is given to us in the question area for which the paint is just sufficient is 9.375. So in order to find out the number of bricks that can be painted with the available paint would be 9.375 divided by the surface area of one brick. So we see that this area of one brick is given by into breadth plus breadth into height plus width that is L equals to 22.5 centimeter, breadth that is V equals to 10 centimeter and height that is H equals to 7.5 centimeter. So now we will simply put in the values here and we will find the surface area of one brick. Now we see that in the question we are given the area in the units of meter square. So we convert this also into meter 22.5 divided by 100. Now we divide it by 100 because we are converting it to meters multiplied by 10 by 10 to 7.5 divided by 100 plus 7.5 divided by 100 meter square. Now from all these terms we can take 1 upon 100 into 1 upon 100 common. So we have 2 into 1 by 100 into 1 by 100 multiplied by 22.5 into 10 will be 225 into 10 will be 225 and 7.5 into 22.5 will be 168.75 meter square. Now we see that 2 into 50 gives us 100. So we have 1 in the numerator and 15 in the denominator and this becomes 1 divided by 15 to 100 is 5000 multiplied by 225 plus 75 plus 168.75 is 468.75 meter square and that is equal to 0.09375 meter square. Now divided by the surface area of 5 divided by 0.09375 that is equal to once we get it to gets multiplied by 100,000 and the denominator gets multiplied by 1000. See that 9375 gets cancelled with 9375 and 1000 into 100 gives us 100,000. So this will give us 100. So the number of bricks that can be painted will be 100. So our answer to this question is to the question and enjoyed the session. Have a good day.
