Provide an Appropriate Response $V = \frac { 1 } { 3 } h \left( a ^ { 2 } + a b + b ^ { 2 } \right)$

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, $\mathrm { a }$ is the length of the top, and $\mathrm { h }$ is the height. Try to visualize the figure if $a = b = h$ . Calculate the volume if $a = 296$ feet, $b = 296$ feet, and $h = 296$ feet.
