Question

find the surface area of a cube whose measure is 4 cm .20 solve 3 x + 4=0​

Answer 1

Cube has 6 faces. The surface area of a cube which has a side of 4cm is 6*4^2=6*16 cm^2.

Answer 2

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.
