New dude in town and don't know how to create the following complex (at least
to me) formula to calculate LV MASS in excel . . .

lv mass = 1.05 x {(b+t)^[2/3 (a+1) + d ~ d3 / 3(a+t)^] - b^[2/3 a+d ~ d3 /
3a^]}

note that d3 is d cubed

any assistance is most helpful ... under pressure to solve this ASAP

Someone pls show me the way . . .
