A square base

A solid right pyramid has a square base. The base edge length is 4 centimeters, and the pyramid's height is 3 centimeters. What is the volume of the pyramid?

Correct answer:

V =  16 cm³

Step-by-step explanation:

$$\begin{gathered} a=4\text{cm} \\ h=3\text{cm} \\ {S}_1=a^2=4^2=16{\text{cm}}^2 \\ V=\frac{1}{3}\cdot S_1\cdot h=\frac{1}{3}\cdot 16\cdot 3=16{\text{cm}}^3 \end{gathered}$$
