Area of a triangle= base • height/2;
A=17•4/2= 17•2=34 ft^2
The side length of the base of the souvenir is 9cm.
A square pyramid -shaped souvenir has a volume of 216 cm^3
and the height is 8 cm.
What is square pyramid ?
A three - dimensional geometric shape having a square base and four triangular faces/sides that meet at a single point (called vertex) is called a square pyramid. It is called a pentahedron, due to its five faces.
Now, Using the formula of Volume of square pyramid
V =
Solving for a
a ==
a = 9cm
Thus, The side length of the base of the souvenir is 9cm.
