Multiple Choice

Provide an appropriate response.
-The formula used to find the volume of the frustum of a square pyramid is $V = \frac { 1 } { 3 } h \left( a ^ { 2 } + a b + b ^ { 2 } \right)$ where $\mathrm { b }$ is the length of the base, $a$ is the length of the top, and $\mathrm { h }$ is the height. Visualize the figure if $a = b = h$ . What would the figure be?

A) A cone
B) A sphere
C) A cube
D) A cylinder
