Volume = are base*height
32 = x^2*h --> h = 32/x^2
surface area = 4x(32/x^2) + x^2
SA = 128/x + x^2
SA' = -128/x^2 + 2x = 0
2x = 128/x^2
2x^3 = 128
x^3 = 64
x = 4
surface area minimized when length of base is 4 in.
hope this help
Lets find out...
a^2 + b^2 = c^2
27^2 + 79^2 = 84^2
729 + 6241 = 7056
6970 = 7056....incorrect....no, it is NOT a right triangle
