The original dimensions of the cardboard is 21 cm × 21 cm, if a square pieces with lengths of sides of 6 cm were cut out of corners of a square piece of cardboard and the volume of the resulting box is 486 cubic centimeters.

Step-by-step explanation:

The given is,

Square pieces with lengths of sides of 6 cm were cut out of corners of a square piece of cardboard.

The volume of the resulting box is 486 cubic centimeters.

Step:1

The volume, is the given piece of cardboard was folded into an open box, we calculate side value of cardboard after cut into a square piece,

Formula for volume of cardboard is,

Volume, V = whl ......................(1)

Where, w - width

h - Height

l - length

From given, V= 486 cubic centimeters

h = 6 cm ( Ref attachment)

w = l

Equation (1) becomes,

$486=6(l^{2} )$

$l^{2} = 81$

Take root on both sides

l = 9 centimeters

Step:2

Ref the attachment,

Side value of piece of cardboard

= 6 + 9 + 6

= 21

Side value of piece of cardboard = 21 centimeters

original sides of cardboard is 21 cm × 21 cm

Result:

Four congruent square pieces with lengths of sides of 6 cm were cut out of corners of a square piece

Answer from: Quest

First subtract 10 from both side
y^2+6y-16=0
(y+8)(y-2)=0
-8 and 2

Answer from: Quest

step-by-step explanation:

if you want to separate 54 into 6 individual tiers then you need to divide if you want to separate 54 into 6 individual tiers then you need to divide 6 and 54.

you will get 9.

if you divide 9 by 6 you will get 54.
