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:

a=4 cm h=3 cm  S1=a2=42=16 cm2  V=13⋅ S1⋅ h=13⋅ 16⋅ 3=16 cm3a=4 \ \text{cm} \ \\ h=3 \ \text{cm} \ \\ \ \\ S_{1}=a^2=4^2=16 \ \text{cm}^2 \ \\ \ \\ V=\dfrac{ 1 }{ 3 } \cdot \ S_{1} \cdot \ h=\dfrac{ 1 }{ 3 } \cdot \ 16 \cdot \ 3=16 \ \text{cm}^3
