A rectangular solid with a square base has a volume of 4096 cubic inches - determine the dimensions that yield the minimum surfa
Bumek [7]

Answer:

side of base, a = 10.1 inches, height, h = 40.1 inches

Step-by-step explanation:

Volume of rectangular solid, V = 4096 cubic inches

Let the side of base is a and the height is h.

V = a^2h\\\\4096 = a^2 h ..... (1)

surface area of the solid  

S = 2a^2 + 4 ah \\\\S = 2a^2 + 4 \times a \times \frac{4096}{a^2}    from (1)\\\S = 2a^2 + \frac{4096}{a}\\\\\frac{dS}{da}= 4 a - \frac{4096}{a^2}\\\\4 a - \frac{4096}{a^2} = 0 \\\\a^3 = 1024\\\\a =10.1 inches

So, h = 40.2 inches

there would be a 99% chance of a red marble being pulled out or even a 1% chance.

because of their being five green marbles and six red there is always a chance you could pull out any one of the colors.

but i believe that both of the answers are 1/2

but im not 100% sure

Answer:

469.42 ft²

Step-by-step explanation:

  • Law of sines;

         w/sin27 = 38/sin40

                   w = sin27*38/sin40

                    w = 26.84 ft

  • Angle x;

            ∡X = 180 - 27- 40 = 113º

  • Area;

              A = 0.5*(26.84)*(38)*sin(113)

            A = 469.42 ft²
