Question

In the cube given below, if one unit cube represents $3^0$, then express what the whole cube represents, as a power of 3?

• A. $3^1$
• B. $3^2$
• C. $3^3$
• D. $3^4$

Answer 1

The correct option is C $3^3$

One unit cube represents $3^0$
$3^0$ = 1
That is 1 cube.
There are 27 cubes in the given picture. ( 3 stacks of 9 cubes)
27 = $3^3$
$\Rightarrow$ The cube represents $3^3$, as there are 27 unit cubes.
