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.
Hope this will help you......✌
