How to find the volume of a pyramid with a square base?
- To find the volume of a pyramid with a square base we can use the formula,
V = a²h/3
where, V = volume of a pyramid with a square base
a = length of side of the square base
h = height of the pyramid.
According to the problem,
- perimeter of the base is 5.7cm.
∴ 4a = 5.7 cm
⇒ a = 1.4 cm
- the height of the pyramid is 8.6 cm.
So, volume of the pyramid = (1.4)² x (8.6)/3 cubic centimeter
= 5.6 cubic centimeter
∴ volume of the pyramid is 5.6 cubic centimeter
