Question

find the side of cube whose curved Surfacea area is 154cm2
​

Answer 1

Let the side of a cube be a cm

As we know that

total surface area of a cube with side a is 6a²

Given total surface area of a cube is 216 cm²

⟹6a² = 216

⟹a² = 36

⟹a=6

So side of a cube is 6 cm

Step-by-step explanation:

Dear Student,

Please find below the solution to the asked query:

Given : Lateral surface area of  cube is 154 cm

, We know lateral surface area of cube = 4 ( Side )

4 ( Side )2=  154

( Side )2= 38.5

Side = 6.20 cm

We know volume of cube = ( Side )3 , So

Volume of a cube whose lateral surface area is 154 cm2 = ( 6.20 )2 = 238.328 cm3 ( Ans )
