Question

A cube with side length 2f is stacked on another cube with side length 3g2. Choose the expression that represents the total volume of the cubes.

Answer 1

the answer is c

Explanation:

Answer 2

The expression that represents the total volume of both cubes is
`8f^3+27g^6`.

The volume of a cube is found by multiplying its length, width, and height; for the first cube, this is
V=(2f)(2f)(2f)=8f³.

For the second cube, this is
V=(3g²)(3g²)(3g²)=27g⁶.

The total area is their sum, so 8f³+27g⁶.
