 Hello and welcome to the session. In this session, we will discuss a question which says that calculate the volume of the rectangular pyramid with length 7 feet, width 4 feet and height 5 feet. Now before starting the solution of this question, we should know a result. Now volume of a prism is equal to area of its base into that is the distance between the bases. Now volume of a pyramid is equal to 1.3 of the volume of a prism. Therefore volume of a pyramid is equal to 1.3 into area of its base into height of the pyramid. Now these results 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 of the pyramid that is b is equal to 7 feet. Then width of the pyramid that is a is equal to 4 feet and height of the pyramid that is height of the a-bikes which is equal to Now from the key idea, we know that volume of a pyramid is equal to 1 by 3 into area of its base into height of the pyramid. So volume of the pyramid is equal to 1.3 into area of its base into the area of the base is equal to length into width. Now length here is 7 feet into width is 4 feet so this is equal to 28 square feet. Now height of the pyramid of its base is 28 square feet. The volume of the pyramid will be equal to 1 by 3 into area of its base which is 28 square feet into height of the pyramid which is which is equal to 140 by 3 cubic feet. So the volume of this pyramid is equal to 140 by 3 cubic feet. And this is the solution of the given question. That's all for this session. Hope you all have enjoyed the session.
