Question

Use the image to answer the question.

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?

(1 point)
ft.3

Answer 1

Cube volume = 3^3 = 27 ft^3.
Prism volume = 1×1×3 = 3 ft^3.
They do not overlap, so total = 27 + 3 = 30 ft^3.
