Question

A colorful cloth is to be fixed on a cubical box. If 864 sq.cm. of cloth is required find the side of the cubical box​

Answer 1

Answer:

Step-by-step explanation:

1+2

4

5 = 2+3

6 = 1+2+3

7 = 3+4

8

9 = 4+5 = 2+3+4

10 = 1+2+3+4

11 = 5+6

12 = 3+4+5

13 = 6+7

14 = 2+3+4+5

15 = 7+8 = 4+5+6 = 1+2+3+4+5

Answer 2

Given: Surface area of the cube = 864 cm²

Let the side of a cube = X cm

6X² = 864

X² = 864/6

X² = 144

X = √144

X = 12 cm

Volume of the cube = X³

V = ( 12 cm )³

V = 1728 cm³

Answer 3

Given: Surface area of the cube = 864 cm²

Let the side of a cube = X cm

6X² = 864

X² = 864/6

X² = 144

X = √144

X = 12 cm

Volume of the cube = X³

V = ( 12 cm )³

V = 1728 cm³
