Given,
The length of the base edge (b) = 5 cm
The height of the pyramid (h) = 9 cm
To find,
The volume of the given pyramid.
Solution,
We can simply solve this mathematical problem by using the following mathematical process.
To calculate the volume of any square pyramid we have to use the following mathematical formula,
= (b)² × h/3
= (5)² × 9/3
= 25×3
= 75 cm³
(This value will be considered as the volume of the given square pyramid.)
Hence, the volume of the given square pyramid is 75 cm³ (option b).
