Question

1. what is the volume of a perfect cube with a length of 2cm?

a) 4 cm³
b) 2 cm³
c) 8 cm³
d) 6 cm³

Explanation:

Step1: Recall volume formula

The volume formula for a cube is $V = s^3$, where $s$ is the side - length of the cube.

Step2: Substitute the side - length

Given $s = 2\text{cm}$, we substitute it into the formula: $V=(2\text{cm})^3=2\text{cm}\times2\text{cm}\times2\text{cm}=8\text{cm}^3$.

Answer:

C. $8\text{ cm}^3$
