A square base

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

Correct result:

V =  16 cm³

Solution:

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