In the Rule of Nines, if both anterior and posterior trunks are burned, what is the total TBSA represented by the trunk region?

In the Rule of Nines, the torso is divided into two parts: the front (anterior trunk) and the back (posterior trunk), and each of these parts accounts for 18% of the total body surface area. If both are burned, you add the two 18% portions together. That yields 36% TBSA for the trunk overall. So, the trunk region represented when both anterior and posterior parts are burned totals 36%. (For context, other regions: head and neck 9%, each upper limb 9%, each lower limb 18%, perineum 1%.)
