Intrigued by this formula, Anne applies it to determine the size of her own dog’s head. Anne again uses the formula relating the estimated shoulder height H (in centimeters) of a dog to the internal dimension of the skull D (in cubic centimeters): H=1.016 D - 31.2.

Anne’s own dog, Baxter, a Welsh Corgi, has a shoulder height of 30 centimeters.

What is the corresponding skull size?
