Solution:
|
|
Volume of a cube = l3
|
|
∴ l3 = 1000 [Given]
|
|
∴ l = 3√1000
|
|
∴ l = 10 cm
|
|
Now,
|
|
Total surface area of a cube = 6l2
|
|
∴ Total surface area of a cube = 6
(10)2
|
|
∴ Total surface area of a cube =
6(100)
|
|
∴ Total surface area of a cube = 600
sq. cm.
|
|
Ans. Total surface area of a cube is 600 sq. cm.
