Question

A cube is made from cardboard 12cmx18cm what is area of 1 face of the cube?

Thanks guys. Could you put formula too?

Answer 1

AREA OF CARDBOARD= 12*18=216CM^2

TO FIND a of cube = 6a^2=216
a^2=36
a=6cm

area of cube 6a^2
= 6*6*6cm^3

total sides of cube=6
therefore area of one side = 6*6*6/6
=36cm^2 (centimetre square)

Answer 2

When A Cube Is Made, It's Drawn On A Piece Of Material, And Folded...

The Most Common Way To Draw It Is To Draw Six Boxes In The Shape Of A Crucifix (Christian Cross)

This Crucifix Would Have 3 Boxes Across And 4 Boxes Down. These Boxes Will End up Being The Faces Of The Dice When The Dice Is Ready.

With The Dimensions Given,
12cm/3 = 4cm
18cm/4 = 4.5cm

So We Pick The Smaller Of The Two Values, As The Width Cannot Be 4.5cm

Therefore, The Area Of One Face Is 4cm X 4cm = 16cm²

Answer 3

Most of the guys above me answerd correctly, I'm just gonna clear it up and give you a faster way of solving this.

You're given a piece of cardboard that has the dimensions 12cm x 18 cm. The total area of the cardboard is also the total area (the area of all the faces of the cube). A cube has 6 faces, so you just divide the total area by 6.

So you've got:
12cm x 18cm = 216cm^2 (centimeters squared)
216cm^2/6 = 36cm^2.

Hope that helps!

Answer 4

Which of the 11 patterns of squares that fold up to make a cube are you going to cut from the cardboard? Is the job to maximize the area? Are diagonal cuts allowed? Can edges be joined only along the edges of the squares?

In simplest form, cut the rectangle into 2 rows of 3 squares, each square 6x6. Join at edges in any of the patterns you want. Each 6x6 face has an area of 36 cm².

Answer 5

let the edge of the cube x
therefore, the area of 1 face of the cube will be: x^2
cube has 6 faces: area of cube = 6x^2

the total area of the cardboard = 12 * 18 = 216

therefore, 6x^2 = 216

x^2 = 216/6 = 36
area of 1 face of cube = 36

Answer 6

A cube has 6 faces.

The 12 cm by 18 cm piece of cardboard can be divided into 6 squares (or faces for the cube) that are 6 cm by 6 cm.

The area of one of the faces is A = (length)(width) = (6)(6) = 36 cm^2.

Answer: 36 cm^2

Answer 7

If we cut the cardboard into identical faces to construct a cube, we'll have six 6cmx6cm squares. Each face will thus have an area of 36 cm (area = length x width = 6 x 6 = 36).

Answer 8

4 x 4 = 16 cm^2
Formula: (L/3)^2, where L is the measure of the shorter side of a cardboard.
----------
When you make a cube from cardboard, you have to cut four small squares plus some extra materials. If you use all the materials, it is theoretically possible. But show a way to do that. It must be very inconvenient.

Answer 9

you messed up, a cube has equal dimensions.

Oops, I think I misunderstood.

12 x 18 = 216
216 / 6 = 36

all 6cm h/w/d
