Area of one face of the cube = 81 m²
As we know,
1 face of cube = Square
Let the side of Sq. be x
A.T.Q. [According to Question]
[Area of sq. (Side × Side) = 81 m²]
=> x × x = 81
=> x² = 81
=> x = √81
=> x = 9
•°• Side of sq. = 9 m
As,
1 Side of sq. = 1 Side of cube
[Volume of cube = a³ “where a = side”]
•°• Volume of cube = a³
= (9)³ m³
= 729 m³
