 Hello and welcome to the session. In this session, we will discuss a question which says that in a class of real model, students are supposed to prepare different three-dimensional figures with the help of molds. Each student of the class chooses one figure, one chooses modes of the shape of a triangular prism. He will choose six modes of the shape of a triangular prism. The base and altitude of the triangular prism at the mold are 4 centimeters and the distance between the two triangular prism at the mold is 8 centimeters. And the amount of play he will need to make six triangular prisms of play. Now before starting the solution of this question, we should know a result. And that is the value of any prism is the product of the area of the base and the distance between the two bases and area of the triangle is equal to half into base into height. Now this result will work out as a key idea for solving out the given question. And now we will start with the solution of the given question. Now it is given a equation that John has modes of the shape of triangular prism at the base of the triangular prism 4 centimeters. The triangular base is equal to 4 centimeters and distance between the two bases is equal to 8 centimeters. And this is the base P of this triangular base of the given prism. And this is the height or altitude of this triangular base. Now from the key idea we know that volume of any prism is the product of area of the base and distance between the two bases. And also it is given that area of the triangle is equal to half into base into height. Now here this mode is in the shape of a triangular prism. So volume of the mode will be equal to area of the triangular base into distance between the two bases. Now the triangular base will be equal to into base into height of base D is equal to 4 centimeters and height H is equal to 4 centimeters. Now putting these values here this is equal to half into 4 into 4 now 2 into 2 is 4 and 2 into 4 is 8. So this is equal to 8 centimeters square. Now distance between the two bases is given as 8 centimeters. So the volume of the mode equal to area of the triangular base which is 8 centimeters square into distance between the two bases that is equal to 8 centimeters. So this is equal to centimeter cube. That is the volume of this triangular prism is equal to 64 centimeter cube. This means that the amount of clay used in one clay mold is 64 cubic centimeters. Such molds amount of clay required will be equal to 6 into the amount of clay required for one mold which is equal to 64 cubic centimeters. So this is equal to 384 cubic centimeters. Therefore joint required 84 cubic centimeters solution of the given question. And that's all for this session. Hope you all have enjoyed the session.
