A box with a square base and no top is to be made from a square piece of carboard by cutting 7 in. squares from each corner and
mojhsa [17]

Answer:

The size of the cardboard should be  26  in\ by\ 26in

Step-by-step explanation:

The diagram for this question is shown on the first uploaded image

     The volume of the box is  V = 2527  \ in ^3

The length and the Width of the card is  

      L = W = Z

From the question we are told that 7 in squares were cut from each corner

So the length and the width of the box  would be  

              L = W = (Z - 7)

And the height would be  H  =  7 in

Mathematically the volume of the box can be represented as

              V  = Length\ of\ bx  * Width\ of\ box * Height\ of\ box

So the Volume would be

         V =  (Z-7)(Z-7) * 7

Substituting values

         (Z-7) ^2 = \frac{2527}{7}

          (Z-7) ^2 = 361  

          (Z-7) ^2 = 19^2

=>   Z - 7 = 19

        Z = 19 + 7

         Z =26 \ in

Find the volume of a cylinder with a radius of 4 in and a height that is 3 times the radius
german

Answer:

Volume of a cylinder: V = π * r² * h ,

Base surface area of a cylinder: A_b = 2 * π * r² ,

Lateral surface area of a cylinder: A_l = 2 * π * r * h ,

Total surface area of a cylinder: A = A_b + A_l ,

Step-by-step explanation:

So, when the radius is tripled, the volume will be 3 squared = 9 times than the previous one.
