Question

How much cardboard is needed to make a cubical box of 8 cm side

Answer 1

SIDE = 8cm.


Cardboard is needed to make a cubical box

Total surface area =6a^2

=6(8)^2

=6*64

=384cm^2

card board is needed to make the box =384cm^2

mark me brainlist if my answer is right

Answer 2

Answer:

$384 cm^2$

Step-by-step explanation:

We are supposed to find How much cardboard is needed to make a cubical box of 8 cm side

So, we are required to find the total surface area of cube

Total surface area of cube = $6x^{2}$

Where x is the side of the cube

So, Total surface area of cube = $6(8)^{2}$

                                                   = $384 cm^2$

Hence 384 square cm cardboard is required  to make a cubical box of 8 cm side
