L²+B²+H² = (50√2)² , also TSA = 2(LB+BH+HL) = 9400 , Now we know that (L+B+H)² = L²+B²+H²+ 2(LB+BH+HL) = 5000+9400 = 14400 , thus (L+B+H) = 120 , sum of four lengths , four bases and four heights = 4*120 = 480 units. 🍻

total profit= (n%*n*40)+((100-n)%*(80-n)*40

We need to find out min value of this

After solving this the final equation wud b  2(n^2) -180n +8000

This will reach min val at n=45

Put this into Total Profit Equation

we get Total profit=1580
