Question

Find the surface area of cube whose volume is 729m^3​

Answer 1

Step-by-step explanation:

given that volume of cube is 729 cube m

volume of cube = side × side×side= 729

so side = 9 meter

curved surface area = 4×side× side = 4×9×9 = 324msq.

total surface area = 6×side ×Side=6×9×9=486m sq.

Answer 2

Answer:

side=√729

=9m

surface area of cube=6a×a

=6×(9×9)

=6×81

=648m
