 Hello and welcome to the session. In this session, we discussed the following question which says the volume of a block of gold is 1 meter cube. If it is hammered into a sheet to cover an area of 1000 meter square, find the thickness of the sheet. Before moving on to the solution, let's recall the formula for the volume of a cuboid. This is equal to L into B into H or we can also say this is equal to area of the base of the cuboid into H. L is the length of the cuboid, B is the width of the cuboid, H is the height of the cuboid and we have the area of the base of the cuboid is equal to length into width of the cuboid. This is the key idea for this question. Let's move on to the solution. We are given the volume of the block of gold is equal to 1 meters cube. Block of gold is cuboidal in shape so this means that the length into width into height of the block of gold is equal to 1 meter cube. We are given that the block of the gold is hammered into a sheet and we have the area of the sheet is equal to 1000 meter square. Now since L into B into H is equal to 1 meter cube so this means that area into H is equal to 1 meter cube. Now we have the area of the sheet is 1000 meter square so 1000 meter square into H is equal to 1 meter cube. Now this gives us H is equal to 1 meter cube upon 1000 meter square. This is equal to 0.001 meters. Here this H is the thickness of the sheet so we get thickness of the sheet is equal to 0.001 meters. Hence our final answer is 0.001 meters. So this completes the session. Hope you have understood the solution for this question.
