You need to measure five dimensions of the metal gate at the given coordinates, rounding each measurement to the nearest whole number.
Height of gate = AB inches
Width of gate = CDE centimetres
Depth (thickness) of gate = F inches
Height and width of grid squares = G centimetres
Vertical gap between bottom two bars of gate = HK centimetres
Checksum (AB + CDE + F + G + HK) = 167
