Answer:
We get
$225+324+441+576+784+1125+2304+3136+4900+11025=24840$
Step-by-step explanation:
$(1\cdot 3\cdot 5)^2 = 15^2 = 225$
$(1\cdot 3\cdot 6)^2 = 18^2 = 324$
$(1\cdot 3\cdot 7)^2 = 21^2 = 441$
$(1\cdot 4\cdot 6)^2 = 24^2 = 576$
$(1\cdot 4\cdot 7)^2 = 28^2 = 784$
$(1\cdot 5\cdot 7)^2 = 35^2 = 1125$
$(2\cdot 4\cdot 6)^2 = 48^2 = 2304$
$(2\cdot 7\cdot 7)^2 = 56^2 = 3136$
$(2\cdot 5\cdot 7)^2 = 70^2 = 4900$
$(3\cdot 5\cdot 7)^2 = 105^2 = 11025$
We get
$225+324+441+576+784+1125+2304+3136+4900+11025=24840$
