Question

Ipereras
If the perimeter of one of the faces of a cube is 40 cm,
then in volume is
​

Answer 1

see, given, perimeter of cube of one side=40

so, 4s = perimeter

s=40/4=10

now , we get side,,, volume = side *side*side

v=1000

Answer 2

Step-by-step explanation:

P = 4s

40 cm = 4s

(40 cm)/4 = (4s)/4

(40/4) cm = (4/4)s

10 cm = (1)s

10 cm = s

The volume V of a cube is given by the formula V = e³

= (10 cm)³ since e = s = 10 cm.

= (10)(10)(10) cm³

= (100)(10) cm³

= 1,000 cm³ is the volume of the cube in which one of its faces has a perimeter of 40 cm.
