Kenard takes a square piece of cardboard and cuts 4 in. by 4 in. squares out of each corner. he folds the sides up to make a box without a top. what equation can kenard use to determine the volume of the box, where x is the side length of the original piece of cardboard

Step-by-step explanation:

Since original square has sides x,

when we cut 4 units from all the 4 sides the box will have height of 4 units.

Length of the box = side of square - 2 times square side cut

= x-2(4) = x-8

Similarly width of the box also would be

x-8

Hence volume of the box = lwh

= length x widthx height

Now substitute for each in terms of x

Volume =

a is the correct

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
