The portions of a house that need to be heated can be modeled by one rectangular prism with a length of 45 feet, a width of 20 feet, and a height of 18 feet, and a second rectangular prism with a base area of 350 square feet and a height of 9 feet. what is the total volume?

To figure this one out, you just have to multiply the length times the width times the height of the first prism so find the volume of it. 45 times 20 times 18 equals to 16,200. you then multiply the 350 by the 9 to get the volume of the second prism. that totals to 3,150. you then add them up and get 19,350 as your answer.

3units/ 5 feet = 60 units/ 100 feet3 units/ 5 feet = 18 units/ 30 feetthe dimensions of the scale drawing are 60 units by 18 units.hope this !
