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 $b$ is the length of the base, $a$ is the length of the top, and $h$ is the height. Calculate the volume if $a = 263$ feet , $b = 698$ feet , and $h = 192$ feet.
