An illustration shows a rectangular prism, placed vertically, on the top corner of a larger cube. The length and width of the prism is 1 foot respectively and the height is 3 feet. The sides of the cube are 3 feet.
What is the volume of the composite figure?
Write yur answer in ft.^3
The volume of the rectangular prism can be calculated as length x width x height = 1 foot x 1 foot x 3 feet = 3 ft^3.
The volume of the cube can be calculated as side x side x side = 3 feet x 3 feet x 3 feet = 27 ft^3.
Therefore, the total volume of the composite figure is 3 ft^3 (prism) + 27 ft^3 (cube) = 30 ft^3.
