Question~ Find the surface area of a cube whose measure is 4 cm. —————- Given : Side of Cube = 4 cm To find : Surface Area Solution : Surface Area of Cube = 6a² = 6 × 4² = 6 × 16 = 96 Therefore, the Surface Area of Cube is 96 cm². Question~ Solve 3x + 4=0 —————- Given : 3x + 4=0 To find : value of x Solution : 3x + 4 = 0 3x = -4 x = -4/3 Therefore, the value of x is -4/3. Reply
Question~
Find the surface area of a cube whose measure is 4 cm.
—————-
Given :
To find :
Solution :
Surface Area of Cube = 6a²
= 6 × 4²
= 6 × 16
= 96
Therefore, the Surface Area of Cube is 96 cm².
Question~
Solve 3x + 4=0
—————-
Given :
To find :
Solution :
3x + 4 = 0
3x = -4
x = -4/3
Therefore, the value of x is -4/3.
Cube has 6 faces. The surface area of a cube which has a side of 4cm is 6*4^2=6*16 cm^2.
